NT8B - Leon Comments - Answer Overflow

On your question about modifications, it's possible that this printer actually may not have the stock stepper motors installed. I'm not able to access the printer until Tuesday this week to verify, but looking at records I can find online, it appears that this printer has stepper motor specifications as follows:
NEMA 17. 0.9° Step Angle. 400 Steps Per Revolution. 2.8V Rated Voltage. 1.68A Phase. 4.4kg/cm (61oz/in) Holding Torque. 48mm Body. 5mm Output Shaft. Looking at the values given above, I'm wondering if the upgraded OS is expecting steppers with a step angle of 1.8 degrees? Otherwise, there are no other modifications to the motion hardware in this printer. If this is the likely problem is it possible to adjust for this in the configuration wizard?

x- and y-axis positioning incorrect after upgrading to RatOS v2.1-RC1

OK, just got done with the reinstall process, and all looks good. Thank you again! I'm now back to the original problem, namely that the x- and y-axes movements are limited to the left rear quadrant of the build plate. Picking up where we left off, I'm attaching the debug.zip file.

Thank you Mikl! There's no need to apologize. I think you and the rest of the team are doing wonderful work. I'll do another install and will report back on how it goes.

x- and y-axis positioning incorrect after upgrading to RatOS v2.1-RC1

Thanks for getting back to me. Unfortunately, I decided to try a clean re-installation of the OS under the assumption that it might clear up my issue. It turns out that seem to have dug myself into a deeper hole. The issue I have now is that when I run through the v2.1 configuration process I cannot get past the firmware installation step. I keep receiving version mismatch errors. I've tried three firmware update methods available in the configurator. I first tried using the autoflash method. When the autoflash process completed, I received the following message:

Ok. I wondered about rotation distance as well but I’m not sure how to tackle it. I’ll rerun the configurator and if that doesn’t work maybe I will try another clean installation. I successfully upgraded a vCore200 last week and it works fine. Thanks for your comments. It’s greatly appreciated.

Yes, the printer will home all axes, and z-tilt as well. Probing for the z-tilt covers only the back-left quarter of the build area.

Extruder not working

I haven't yet created any gcode files in the slicer for this printer. The issue I have occurs when I send extrude or retract commands from the mainsail console.

No trigger on z after full movement

OK - I'm not sure what happened but I'm now getting movement as expected on the z-axis when I home z. I went through a process of checking and re-seating the motor connectors so maybe that was part of the problem? I don't know... Anyway, it looks like I can proceed with adjusting the height of the sensor and the rest of the setup process. I'm very grateful for your help. Thank you for being there.

Stand by and I'll double check. I can confirm that the coupler/leadscrew is properly tightened.
