HE280 Hot End and Probe board on RMAX v2

[bvandiepenbos]

Finally got my hands on the new hot end and probe board to test out on the MAX v2
Made aluminum effector platform to mount it with ball cup arms.
Just downloaded newest Repetier fw and getting ready to flash it to machine.
Still figuring out the wiring...

Is this the new one from the Eris?

Forget the wiring.... I want to know when you're going to sell that effector platform and those sexy ball cup carbon fiber end tips!!!

[bvandiepenbos]

Is this the new one from the Eris?

yes, it is from the Eris.
I hear it will be standard on the RMAX v3 kits to be available in a few months.
And the hot end + probe board as a retrofit kit for older machines.

[davec3275]

Sweet!! Maybe now I can finally use my RMax v2 properly.

I have a few of the aluminum platforms available now that I milled on my CNC. I expect to have a batch of (50) from my local water-jet guy in a few weeks.

Beta testing of the rod ends is complete, they work great! I am very close to pulling the trigger on the injection mold for those ends, just need to check over the design details before committing to the hard tooling investment. They will be injection molded Delrin.
I designed our new ball-cup rod end to be a drop-in replacement for the Traxxas ends used now on our CF arms. They will be available separately for people that already have our CF arms to convert to ball-cup by simply unscrewing the Traxxas and gluing the ball-cup rod ends in place.
They will become standard on our new CF arm sets, as will the springs... no more rubber lash straps.
The balls are 3/8", the same size as the SeeMeCNC ball joints, so you can use them with the stock RMAX white plastic bar-bells.
You can literally pop the stock arms off and pop our Carbon Fiber Ball-joint Arms in place.
I am working on metal ball alternatives also, but I have not figured out a satisfactory solution that is accurate and reasonably priced. So, to begin with we will be using the white plastic bar-bells. ...they are pretty good, but I think they flex a bit, I really would like a stiffer metal alternative.

What about the different arm lengths of the different SeeMeCNC arms?

Also, the white dumbells actually were a big improvement in print quality over the old U-joints. When I installed them, I got a dramatic improvement in fine details in my prints. I'm not sure how much those flex, but I'm pretty sure the SeeMeCNC arms are not as rigid as carbon fiber, so that might be really good for most users.

I'm looking forward to your new products!

They're injection molded glass-filled nylon. There's no realistic reason to replace them other than for asthetics(sp).

Nice effector Brian!
One question, can this new probe board be used with the E3D V6 or others hotends?

[dmgdispenser]

Nice effector Brian!
One question, can this new probe board be used with the E3D V6 or others hotends?

nice, i'm also interested in finding out if that probeboard is usable with other hot ends, e3d v6 and others. thanks =)

[bvandiepenbos]

I think you could use it with other hot ends if probe pcb board was mounted at top of hot end, possibly under the bowden fitting?
The hole in pcb is only 7mm diameter, so the bowden collet should just fit through.
May be better to use another set of short standoffs on top of 3 holding groove mount, mount board to those.

[travelphotog]

There has been testing done with the E3d V6 and the probe board (a bird tells me) and it works just fine. With the board mounted above the hot end it looks close to the Yellow Jacket and there is talk about doing connections from it also. But as of now the narrow hole in the board it a limiting factor for wiring and such. But it does function from what I have been told. Time will tell when the units are out for testing I guess.

[Xenocrates]

In theory, it should be able to be used like the HE280 is, as the heatbreak of the E3D will fit through the board. However, at that point you would need to wire it to the board, as there is otherwise not enough space for it. Of course, I'm just going by CAD models, not by experimentation. I think the Volcano would fit better, as there is a little more room for the wiring to droop that way.

[d1rron]

That's awesome that it will (probably) work well with the E3d V6, but what about the Prometheus V2!? I'd be interested in the board if it were compatible.

The ball cup ends are getting closer to release. Still working out details with the injection molding company.

[Jetguy]

Still extremely interested the in instant you think you have the injection molded ball arms ready. I need a custom set of 340mm long arms ASAP.

[bvandiepenbos]

Injection mold is being built now.
I expect to have first batch of molded rod ends in 3 weeks.

Brian - if you need a hand with the wiring, or firmware, I can help you out. Send me a message and I'd be happy to.

As for using it with a v6, yes you can. I have it mounted above mine, using one of the top screws on my 713maker hotend mount to hold it in place, the bowden is routed through the middle.

Challenges with mount it like that is that, especially if you have a flying extruder, it's easy to cause effector tilt. Even a little tilt is a BIG deal with the accelerometer, and will throw off your calibration big time. Cable drag, or the bowden dragging on the center, can be enough to throw it off.

Once you sort all of that, as long as it's oriented right and cabled right, and solidly mounted, it works great. Calibration to an accuracy of +/- 0.01mm per probe point.

The firmware from seemecnc replaces G30 so you can't probe arbitrary points, it just does a 4 point calibration routine (equivilent to the "standard" calibration). If you want to be able to probe arbitrary points, I can post the bits I added to g30 in order to do so. I use it with the Delta Least Squares calibration website, and can print a 210mm circle completely flat, it calibrates down to a 0.02 deviation in 3 runs.

[kraegar]

Here's a pic of it above my E3D v6, when I had my extruder in a "flying" config - I've since switched away from that, but haven't changed how I mount the probe. Just a cheap nylon spacer to provide some clearance for my hotend wires.

[kraegar]

Oh, I also find I get better accuracy calibrating with both the hotend and bed at printing temps. However, you have to be sure the hotend is completely clear of all filament, and the bed is spotless, too. Any melted filament will cause your doduble-tap probe to fail with too great of a variation between checks.

[TwoTone]

Sorry to piggy back onto this. When you added the probe board and uploaded the new firmware, were there any changes needed in the setting?

When I was looking at the firmware here: https://github.com/seemecnc/Firmware/tr ... 20Firmware
I noticed it mentioned inverted motors.

So I was wondering what setting changes are needed to use the probe board on the V2.

Thanks.

[kraegar]

Hopefully Brian doesn't mind me tagging in here. Since I've been updating regularly for a while now, to keep up with the changes as they release them, here's what I change for my particular setup (rostock max v2, e3d v6, e3d titan) - your changes may vary.

Configuration.h:

Code: Select all

42: #define MOTHERBOARD 301 //RAMBO AJA
50: #define PRINTER 2 //Rostock Max v2 AJA
118: #define EXT0_TEMPSENSOR_TYPE 8 //changed to 8 for e3d v6 from default 97 AJA
123: #define EXT0_INVERSE 0 //changed to 0 from default 1 for titan AJA
258: #define MAXTEMP 290             //  this is the max allowable temp the hotend can be set at, any higher will trigger safety's // Changed to 290 from default 245 for e3d v6 AJA

To add probing any arbitrary point, I use the following for "case 30" (the bulk of the changes other than a closing brace are at the top) in commands.cpp:

Code: Select all

    case 30: // G30 single probe set Z0
    {
#if DISTORTION_CORRECTION
        float oldFeedrate = Printer::feedrate;
        Printer::measureDistortion();
        Printer::feedrate = oldFeedrate;
#else
        float sum = 0, sum1 = 0,last,oldFeedrate = Printer::feedrate, offsetmm = 0; //add ofsetmm = 0 AJA
        bool oldAutolevel = Printer::isAutolevelActive();
  if((com->hasS() && com->S == -1) && (com->hasX() && com->hasY())){
	Printer::homeAxis(true,true,true);
	GCode::executeFString(Com::tZProbeStartScript);
	Printer::setAutolevelActive(false);
	Printer::moveTo(com->X,com->Y,IGNORE_COORDINATE,IGNORE_COORDINATE,EEPROM::zProbeXYSpeed());
	sum1 = Printer::runZProbe(true,false,Z_PROBE_REPETITIONS,false); //First tap Y tower
        sum = Printer::runZProbe(true,false,Z_PROBE_REPETITIONS,false); //Second tap Y tower
        if ((sum1 - sum) > .1 || (sum1 - sum) < - 0.1){
          Com::printErrorFLN(Com::tZProbeFailed); //output to terminal Z probe failure
          sum = -1; // fail flag to stop probe
        }else{
            offsetmm = sum - Z_PROBE_BED_DISTANCE;
	    Com::printFLN(PSTR("Probed offset in mm "),offsetmm);
            Printer::homeAxis(true,true,true);
	}
  }else{
    //Back to normal seemecnc g30 AJA
    do{
        if(com->hasS() && com->S == 2){ // only reset eeprom if saving new value
        Printer::zLength = Z_MAX_LENGTH; // set Z height to firmware default
        EEPROM::storeDataIntoEEPROM(); // store default before calibration
        EEPROM::readDataFromEEPROM(); // would not take effect unless read!
        }
        Printer::homeAxis(true,true,true);
        GCode::executeFString(Com::tZProbeStartScript);
        Printer::setAutolevelActive(false);
        Printer::moveTo(0,0,IGNORE_COORDINATE,IGNORE_COORDINATE,EEPROM::zProbeXYSpeed());
        
          sum1 = Printer::runZProbe(true,false,Z_PROBE_REPETITIONS,false); // First tap
          sum = Printer::runZProbe(true,false,Z_PROBE_REPETITIONS,false); // Second tap
          if ((sum1 - sum) > .1 || (sum1 - sum) < - 0.1){ //tap reports distance, if more or less than .1mm, it will re-run
              Com::printErrorFLN(Com::tZProbeFailed);
              sum = -1;
          }
    }while(sum < 1);
        if(com->hasS() && com->S)
        {
#if MAX_HARDWARE_ENDSTOP_Z
#if DRIVE_SYSTEM==DELTA
            //Printer::updateCurrentPosition();
            Printer::zLength += sum - Printer::currentPosition[Z_AXIS];
            Printer::updateDerivedParameter();
            //Printer::homeAxis(true,true,true);
#else
            Printer::currentPositionSteps[Z_AXIS] = sum * Printer::axisStepsPerMM[Z_AXIS];
            Printer::zLength = Printer::runZMaxProbe() + sum-ENDSTOP_Z_BACK_ON_HOME;
#endif
            Com::printInfoFLN(Com::tZProbeZReset);
            Com::printFLN(Com::tZProbePrinterHeight,Printer::zLength);
#else
            Printer::currentPositionSteps[Z_AXIS] = sum * Printer::axisStepsPerMM[Z_AXIS];
            Com::printFLN(PSTR("Adjusted z origin"));
#endif
        }
        Printer::feedrate = oldFeedrate;
        Printer::setAutolevelActive(oldAutolevel);
        if(com->hasS() && com->S == 2)
            EEPROM::storeDataIntoEEPROM();
        Printer::updateCurrentPosition(true);
        printCurrentPosition(PSTR("G30 "));
        GCode::executeFString(Com::tZProbeEndScript);
        Printer::feedrate = oldFeedrate;
        Printer::homeAxis(true,true,true);
#endif
    }
    } //close my if AJA
    break;

Those are the only changes I need to make before I upload my firmware and start calibrating / printing.

Edit: to probe an arbitrary point, then, you have to send a G30 S-1 X0 Y0.... the S-1 is what triggers my bits to run, otherwise it's just the standard seemecnc implemented bits. I did that so I didn't break any instructions they provide. Here's my 10 probe points to use with the Delta Least Squares page here: http://escher3d.com/pages/wizards/wizarddelta.php (use a printable radius of 142.68, you want the tower probe hitting nearly straight down, or it's going to be way off).

Code: Select all

G30 S-1 X0.0 Y142.68
G30 S-1 X123.56 Y71.34
G30 S-1 X123.56 Y-71.34
G30 S-1 X0.0 Y-142.68
G30 S-1 X-123.56 Y-71.34
G30 S-1 X-123.56 Y71.34
G30 S-1 X0.0 Y71.34
G30 S-1 X61.78 Y-35.67
G30 S-1 X-61.78 Y-35.67
G30 S-1 X0.0 Y0.0

And one more, sorry Brian!

Here's a video of the hotend probe hitting X0 Y0, and a custom point (G30 S-1 X123.56 Y71.34)
