Yeah.. and I also had derived values for my thermistors in the other two tables, so the values were different. Nothing made a differences so any time I had a generic table selected though, it just stayed 0°C and wouldn't change regardless of temp.

Just a crazy thought, did you try jumping the thermistors to different thermistor inputs? I vaguely seem to remember having to do that with my rambo when I ran 0.90alpha firmware with it.

Flateric wrote:Sorry about that, yes, I was referring to the firmware revision number not the host version number which are both very confusingly similar in numbering.

I was running 0.90 alpha FIRMWARE, and the commonly available 90c HOST.

But you mention that the 0.91 has just been issued. Are you referring to host or firmware now?

Host.

Well, maybe issued isn't the correct word. But, if you view the changelog for Repetier-Host, a few days ago some changes were made and labeled 0.91.

See https://github.com/repetier/Repetier-Ho ... ngelog.txt

I'm glad to hear that the 0.90alpha firmware is stable enough to use, all usual development-software caveats withstanding. Now I know what I'll be wasting my weekend doing...

Edit: I finally just managed to figure out how to build the Repetier-Host software with xbuild on 'buntu linux! No major, noticeable, changes over 0.90c, though

I did not try that...since the preset tables were working just fine it didn't cross my mind to change inputs.

There's a bug in the code for the generic thermistor tables. After fixing, everything appears to function as expected. Patch:
Caveat emptor: don't blame me when the printer catches fire.

I don't use the generic thermistor tables, this explains why I was not having any issues.

Well after just going through the list I had found whatever #8 was to match really close to my thermocouple so I just had gone with that. I had a print stop at 2:32 before if completed on a 2hr print.....The printer just said 'Idle' and was unresponsive. @#$%! Now I question too many things because the firmware isn't a stable version..*sigh*

I am pumping out print after print now with the alpha code without issues. Turn on ping pong communications. Binary is fine in my testing.

1 big thing I have noted, when the LCD panel is plugged in my problems with errors and canceled print go through the roof. I tried some short ribbon cable and put a ferrite ring on each of them and my problems almost went entirely away. I say almost because I cannot truely trace the one lock I had back to the LCD with shorter cables. But if I switch to the longer ones without the noise reducing ferrite bead I simply cannot use my printer. It WILL lock.

So for now I have simply unplugged my LCD altogether and have had zero issues of any kind.

I am now fully converted into a v0.90 follower. I find it totally stable and has so very many useful features I can no longer do without. (favorite being my often mentioned realtime adjustable delta radius DURING the print in progress. I have never EVER been so dialed in with my delta radius previous to this. It is flawless now because of this feature)

Karl, would you please submit that patch to Roland (Repetier)?

Thanks!

Thanks Flateric, I'll try that. I also have some fairly repeatable (in causing an issue) funny behavior when I had to go through bed leveling in giving the printer quick commands that queued up, such as kill a print and home. Maybe the LCD trick my help it. One time I killed the print and it resumed printing at the top, or sometimes it just get’s downright confused accidently hitting multiple script shortcuts in repetier host. Sadly I still do a lot of recalibrating since my onyx like to warp differently each thermal cycle, I have the SeeMeCNC borosilicate plate on top of the Onyx and it does it regardless of clamping or screw tightness looseness. it’s about to get a complete teardown and more* for misbehaving.

*More being I was given a chunk of scrap aluminum that can be reduced to a 12in circle… the bigger problem than finding someone locally to mill it extremely level is that it is an inch thick… The price was right, the construction guys let me dig in their scrap bin and have it for free .

Gene: I sent a pull request on github. I'll let you know if it gets picked up.

Pull or push?

Yes.

I was writing work instructions and people throw a fit if the document says to open/close a breaker if it says off/on, or vise versa. So I called up to my hoist operator to check the breaker label, and I asked 'Does it say open/close or off/on', his response was 'Yes'... even after I asked it again .

Gene: Roland pulled (as in "accepted") my fix today.

Any sort of a development timeline for this?

The probe has a limit switch type connection to the RAMBo. The wires are not attached yet to the probe shown in the video. I was planning on using a piece of PTFE tube stuck into a hole which would be drilled beside the probe. Picture two wires coming out of the end of the PFTE tubing (like a whip) and leading down to the probe.

The software to integrate this has not been written yet. The algorithm will probe 4 points. One at each tower and one in the center. While the three tower points define a plane, the center point will allow for spherical calculations, like center point and radius. The software stores the new values and begins your print.

This should eliminate the need manually set the z height as well as eliminate the need to manually set the delta radius offset. Basically, this saves you a bunch of time. And if the machine is moved from place to place, you can quickly auto-calibrate and start printing.

Still waiting for the software

Stupid question here. If the Z probe is to be wired, how do you keep it from snagging on things and looking messy?

I'm just a noob, but I would simply put an IR transistor on the effector, and a coin cell and IR led on the Z probe, activated by the microswitch that you already have on it.
Can't remember if the limit switch has a pwr, gnd, and signal input pin designation, but it would work easily if it did. The umbilical cord can handle some tiny wires for the IR transistor/module. I suspect a IR transistor with integrated darlington paired with it will work nicely in a pull-down configuration with a current limiting resistor. Or you can use a photocell, but I don't think it has the response time needed.
If you choose a magnetic reed switch on the effector, and an electromagnetic coil on the battery powered Z probe......that would work, too.
Radio control is a bit overkill, and would probably add too much to the cost of mass production.

Oh gods of 3D, when is it going to happen? My anticipation is giving me panic attacks.

Jeeze, you guys are worse than meth addicts. I dub thee The SeeMeCNC Pinkman Brigade!

Will this really improve print quality that much? I've gotten my bed leveling/z-height to within a few thou, is the probes' tolerance going to be much tighter?

I now have over 350 hours on my machine that I purchased late June. I've had to recalibrate exactly twice - and once was because I installed a new hotend.

How often are you all needing to recalibrate?

I feel like this is either for lazy people or for new machines/users.

I dunno, man, I sure would have loved to have this thing when I discovered the hard way that my print bed was an entire 0.2mm higher when it had been at 95c for several hours. Sure would have saved me a lot of swearing and panic.

Also makes switching extruders basically plug-and-play.

Sorry cope, but some of us like to take our tools with us to solve certain problems at workplaces.....and time is money. So speed of calibration is key. As for my manual calibration.....I have had lathes give me more hell calibrating and zeroing. This one was easy. The first print was spot on perfect. The good instructions on zeroing were very good.

Just remember.....some of us have more than one type of machine to tend to, and need to shave our time down so that other machines can be set up for totally different jobs that have nothing to do with 3d printing.
A 3d printer salesman would agree with this totally. Demos are the stuff with which you bargain with in the tool industry. Makefaire is a perfect example, which is where I saw the Rostock Max in action, and bought the kit later on.
Lazy? No. Busy fixing other machines while this one hums away. I never considered the rostock max a toy.
