Re: Controller options?
I've had pretty good luck (a couple dozen decent prints - haven't been running my printer much lately) running with a Smoothie hooked up to a BBB that's running Octoprint. I was using a Raspberry Pi to run Octo for a while, but the USB/ethernet shared bus made for painfully slow uploads at times, an...

Re: OctoPrint on Beagle Bone Black Rev C
I've been running Octo on a Debian BBB rev C for a few months now after I kept running into random problems with my RasPi. Works fine, and it feels like it's an order of magnitude faster on file uploads (the RasPi USB is a bottleneck), calculating print times, etc. You can use the angstrom-based ins...

Re: How square is square enough
I didn't bother too much with ensuring it's square, if it's off 1 degree you can compensate that anyway when you calibrate it :] Trust me - it's much easier to build it square than to try and calibrate out the non-squareness. I believe Repetier-Firmware can handle rotation of a tower, but it might ...

Re: Unsolved Mystery. Weird Z0 behavior around build perimet
My understanding is that all other things being equal, changing arm lengths tends to affect cartesian X/Y (part scaling) more than Z.626Pilot wrote: Maybe arm length too, but I've found that changing the individual arm length offsets causes only a tiny change for any realistic offset.

Re: The "Taulman Toolbox"
Thanks for the info!

That was special pricing (I think) for backers of the Kickstarter campaign, even though it didn'...

Re: Z-Banding (or uneven layers, ridges in print, etc)
Gaps on perimeters: Your extrusion width parameter might be too big. My 0.4 nozzle usually gets set between 0.41-0.44mm, depending on the specific filament and how fast I'm printing. The wavy patterns - is there any play in your hot end mount? If you push the tip of the hot end, is there any play in...

Re: Onyx R3 "SuperBed" Build
This is what I'm doing over on my Smoothieboard. The board itself including the steppers actually do off 24V. I have a stepdown converter for the hotend and fans. A single 100W-rated converter is more than enough.0110-m-p wrote:Why not just run a single 24V psu and a 24V-12V converter to get 12V to the Rambo?

Re: Octoprint and Repetier-Server for Raspberry Pi?
I usually just print straight from my desktop, but lately I have been wanting to do other heavy CPU stuff on it while printing so I started using the LCD and SD card more so that I don't screw up a 10+ hour print job. The only problem with the SD card is that it takes forever to upload through Repe...

Re: Unsolved Mystery. Weird Z0 behavior around build perimet
626Pilot, since you're running simulations and not actually moving the machine - would it make sense to run the simulation on the host and then use the machine to make periodic validation runs? Your host calibration routine could change any of the needed parameters on the EEPROM and go from there. ...

You're hitting on something that I think is the next big thing in home CNC... Closed loop positioning. It's starting with ZProbes, but eventually I think we'll have it on all movement.

Well, here's a crazy idea: Let's just probe the bed ONCE, and then use brute-force computation to simulate EVERY possible miscalibration within some reasonable range.

Would some one minde sharing gcode of 3riple or double extrusion? It's not a gcode thing - your slicer (and the parts you feed into it) need to be set up. All you do in the gcode is tell it to do a tool change. The slicer should do that. Most common thing today is to use the 2nd extruder for suppor...

So, what is indicated is that, one should change the fans because they will be receiving the input voltage on the rail. What about the motors? As they are current controlled will their PWM values need to be changed aswell? Also, for the fans can i change them in the firmware? Or must I change them?...

Looking at the code in the Temperaturecontrol module in Smoothie, it looks like it would be easy enough to add the code in - just need an if statement to force the integral term to zero outside the desired control band.

They also need to include integral wind-up prevention, which would prevent overshoot at startup. Right now the integral error term can drive you to max_pwm.
