@o_lampe Maybe you can build in a magnetic comb that sits between the glass sheets and move it with magnets from the top side when needed, and leave it along an unlit edge when it isn't needed.

@DuetCDH our support team has no experience with OpenPnP, therefore I have replied in the OpenPnP group thread that you linked to. I can't see any reason why RRF would fail to respond to a command.

If you need to post here again, you should be able to include links now.

@Perplexed Thank you for the positive feedback! I'm glad it worked out well for you 🙂

Hopefully I will find some time to start working on this project again.
I did start to implement the use of a config file to make it more flexible, which I would like to get finished at some point...

@daniel-armstrong When I imagine bottom left, if I'm standing in front of the machine, I'm thinking of the X limit switch on my left, and the Y limit switch closest to me. If this is correct, then both X and Y are homing to the low side.

@daniel-armstrong said in Homing and Axis issues:

M574 X0 P"xstop" ; Set active high X endstop
M574 Y0 P"ystop" ; Set active high Y endstop
M574 Z1 P"zstop" ; Set active high Z endstop

Why X0 and Y0 above? If you intend to have them on the low side of each axis, it should be X1 and Y1.
https://docs.duet3d.com/User_manual/Reference/Gcodes/M574 . I would also recomend setting the S flag as well (unsure if there is a default). Sounds like they should be:

M574 X1 P"xstop" S1 ; X axis homes low side, active high M574 Y1 P"ystop" S1 ; Y axis homes low side, active high M574 Z1 P"zstop" S1 ; Z axis homes low side, active high

Unsure on Z, reused what you had.

What I'm imaging based on "bottom left", is this isn't correct, let me know!

If my thoughts above are correct, then in homeall.g you appear to be moving X and Y in the wrong direction. Again, check my notes above for Z. Some questions:

I see move.axes[0].max2, move.axes[1].max2, move.axes[2].max2 ... is the max2 right? Later you use move.axes[0].max, but I'm not familiar with a max2 in the object model (I'm also not particularly well versed in CNC mode) You're using H1 mode for your homing moves, which is good. I think then that the G92 command is redundant, as H1 is setting position to the limit defined in M208.

@Mark-Markus

Your 48V 1000W supply is perfectly sized.

Are you (man, machine or thing) really sure? Did you not understand @dc42's post above?

@NineMile @Firky_CNC I have created https://github.com/Duet3D/RepRapFirmware/issues/1107. I welcome feedback on this feature request from anyone with experience of controlling spindles over Modbus.

dc42 created this issue in Duet3D/RepRapFirmware open Add direct Modbus spindle control #1107

@Tool88 said in Duet 3 6hc canned cycle:

Also is reprap capable of i-0. J-0. Commands

I see the administrator responded
But I don't see a way to respond to thank you
A i-0.0 and j-.0
Would look something like
G03 x location i-0.234 j-0.0038
It's just a way to cut circle without having to do every arc move as a single step

Yes, RRF supports G2 and G3 using I and J parameters, see https://docs.duet3d.com/User_manual/Reference/Gcodes#g3-controlled-arc-move

@dhusolo yes that should work.

@Alijambo73 yes, see https://forum.duet3d.com/topic/30951/pwm-to-voltage-converter-issues-again?_=1743488505208.

@Jon-vdk I suggest you take a look at https://github.com/Duet3D/RepRapFirmware/wiki/Adding-New-Kinematics.

@meki05 if you don't want to read those sensors independently then you could connect both in parallel to a single temperature sensor input, and set the R parameter in the M308 command to double the standard value to compensate for that. The standard value is 2200 on Duet 3 boards.

@dwuk3d Thank you very much, the problem has been solved.😊 👍

@ojje I think I have figured it out. 🙂

@mendelevium Duet boards and RepRapFirmware support CNC machines. There is a CNC section of the forum (which I've moved this thread to) and a page for setting up CNC machines on the wiki, see https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_CNC

@T3P3Tony I would think that I could get at least double that speed for travel moves; as I understand it that is currently limited by the LinuxCNC controller and not by the motor drivers. I will have to check the current settings and the motor gearing though to be able to answer your other questions.
