@dc42 can you post current post processors on this page?
-
@adamfilip I don't know if David has any CNC mill post processor for the Duet. All I can help you with is the CamBam 1.0 one. I have used it extensively and it is working very well with firmware 2.0 and newer. As I can't upload the file (it's name is Duet3D v2.0.cbpp), here is its content:
<?xml version="1.0" encoding="utf-8"?>
<PostProcessor xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Version="0.9.8.0">

</PostProcessor> -
I asked Ryan from Ooznest about the post processor they use for Duet and they said they just use standard GRBL
-
It may be of interest that RRF 2.02RC7 supports Fanuc-style GCode in the sense that where you have a sequence multiple G0, G1, G2 or G3 commands, after the first line the subsequent lines can just specify the new coordinates (and feed rate if necessary), omitting the G command.

@adamfilip GRBL might work as post processor with the latest firmware, I admit! 8 months ago that was not possible and I have added the dedicated CamBam post processor because of that.
-
With the latest rc7 firmware, fanuc postprocessor should work, I'll make a powermill post and post it here once it's done. It should be pretty easy now. It'll work with featurecam and artcam too.
If you looked for it, any cam should include a fanuc post. -
@dc42 I am currently running the latest firmware on duet wifi but I am getting a bad command error on the line with no G command when running a GCode file. I don't know if I am missing something.
For example:
G1 X100 Y100 F2000
X200 Y200
G1 X0 Y0The gantry moves to X100 and Y100 then back to 0 only

You need to put G1 in front of the X200 Y200

Have you set the machine mode to CNC, using M453 ?
-
I do not have a spindle hooked up to the duet. So if I use the M453 code on its own the GCode works correctly, but if I add the P and R parameter to the M453 it does not. The bad error command pops up. I am running an MPCNC and this is my config. Maybe there is some conflicting commands.

@deckingman Have a look at @dc42's previous post on omitting the G1 command, It was implemented in RRF 2.02RC7 release

Yes thank you. I missed the fact that this was a CNC related question. Apologies.
Edit (but you could try my suggestion because if it improves things then that information might be useful in diagnosing the problem).
-
@moameen, my guess is that the M453 command is failing because of a bad S or P parameter on that command. You can check which mode the machine is in by sending M450. You can also try sending the same M453 command from the GCode console that you have in config.g and see if you get an error message. One possible reason is that you have chosen a pin that is normally used as a heater to control the spindle, but you haven't first made it free by disabling the associated heater using M307.

@moameen Please re-check your axis mapping (M584)! I would strongly suggest that you start with my config.g example and modify it as needed.
Also it is important to differentiate between single homing switch on just one of the Y-axis or separate homing switches on the two Y-axis. What is your actual setup?
More important... how large is your WorkBee and is it screw or belt version?
-
@dc42 I have made the changes and disabled the heaters but i am still having the same problem. when I send the M453 command via web interface, a bad P parameter error is coming up.

@catalin_ro I am running an MPCNC with dual x and dual y motors and separate homing switches on each axis so as to allow the machine to self square during homing.
-
You haven't specified the heater numbers in the M307 commands to disable the heaters.

@dc42 Thanks for the help. All sorted now

@moameen Can you share your config.g and other files? Perhaps running now with 2.05? Building an MPCNC
