gSender vs Universal GCode Sender

gSender ❓ Question
1

Hi
a few years ago I built an Arduino controlled CNC machine and have used the UGS to control the CNC.
I recently stumbled on and I really like its features.
However, I get an error with gSender that I don’t get when I use USG
(See below gCode)

              G0Z20.000H1
              G0X0.000Y0.000S12000M3
              G0X-269.000Y-186.000Z5.000
              G1Z-2.923F1200.0
              ok
              ok
              error:20 (Unsupported command)
              ok
              ok
              ok

I also have a question about the firmware.
Initially I installed the firmware using these instructions GRBL Arduino Library – Use the Arduino IDE to flash GRBL directly to your Arduino | Protoneer.co.nz which is the company that supplied the shield I’m using.

What Firmware I should choose in the Firmware Tab for my machine?

Is the H1 in that line the problem? I’m not an expert by any means but I’ve never seen the H1 before. On my test device I get the error with the H1 but not without. I’m guessing that command is not supported.

@Sammy @_Michael I believe that Michael has hit it. Nothing that I can find shows an H command in grbl. What cam software did you use to create the gcode?

@Sammy To add to this question… What post processor?

I used Cut2d v10.5
the post processor was Gcode ATC (mm)
I took a look at the post processor and it seems the ‘H’ relates to the Post processor, the comments say so :slight_smile:

@Sammy Obviously, I was wrong about the H code. I have no idea if that is causing your issue, but I would bet that @NeilFerreri will know.

Just a question if you don’t mind. Do you have an automated tool changer on your machine?

Hi gwiki
thanks for your help.
I don’t have an automated tool changer, but I do think that post processor is the problem
I cant remember why I chose that one in the first place , but I’m going to try gCode_mm tomorrow and see how that goes

@Sammy That may be a good idea. You can also try grbl mm. This is the one recommended for the arduino-controlled Long Mill. Since your machine is also arduino controlled, it would be a good place to start.
