Unable to run Gcodes from Estlcam in Web control

deckingman

Are those files really OK? I know nothing about CNC so please forgive my ignorance but it looks like "G03 X00.162 Y00.215 I00.004 J-00.009 F01.200" is commanding movement for X, Y, I and J axes yet X,Y U and V are what are in config.g. And feed rate of 01.200?

In G2 and G3 commands, the I and J parameters specify the relative XY coordinates of the centre of the arc.

EDIT: I agree that a feed rate of 1.02mm/min looks low, even for a CNC machine. And I've just remembered that the default minimum feedrate in RRF is 0.5mm/sec i.e. 30mm/min.

@dc42 Ahh OK. - Thanks.

I home Z with G92 Z0, because I have no endstop on Z.

There are some errors in your homing files, although I am not sure they are the cause of the problem. I suggest the following (changes in bold). After making these changes, if it still doesn't work, please check whether you can jog the printer using the jog buttons in Duet web Control, after you have homed it.

I changed the home files for X and Y with your values. Everything works like before. I can home and jog it after homing. What else can I do?

Edit: At some point the Z axis rises unreasonably high and I get the error message "G0/G1 outside machine limits".

dc42

I'll run those files on my bench system. Which firmware version are you running? Send M115 to check.

3DRikat

Thank you. Here's the firmware:

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.03beta2

dc42

I've just run your config.g file, homing files (with my changes) and print file on my bench system. I didn't see any error messages or large Z movements. But the job completed very quickly.

I notice that the movement amounts in the GCode print file are tiny. I've already commented on the very low feed rate. Are the units supposed to be inches instead of mm? I tried inserting G20 at the start and G21 at the end, so that the values would be interpreted as inches, and the job took around a minute.

The print file was from yesterday. I think Estlcam wasn't setup correctly, but now it should be. I just want to test something, to see if it works and then finetune from there. First I want to draw this picture with a pen to see if its square and later I want to try it with the spindle: Estlcam

Maybe you could try the new test file:

Edit: After the outer square is done the Z axis rises unreasonably high and I get the error message "G0/G1 outside machine limits".

dc42

I now get "Error: G0/G1: outside machine limits". The reason is this line:

G01 Z-0.0100 F1200 S1

This commands Z to -0.01 which is below the limit of 0 set by your M208 S1 command. If I send M208 S1 Z-1 before I run the job, then it continues at that point.

When it fails, I don't see a Z movement to a high value. Do you have a cancel.g or stop.g file that might be commanding that movement?

3DRikat

I already tryed to change the M208 command to: M208 X0 Y0 Z-100 U0 V0 S1, but it doesn't help.

This is cancel.g:

; stop.g
; called when a print is cancelled after a pause.

This is stop.g:

; stop.g
; called when M0 (Stop) is run (e.g. when a print from SD card is cancelled)

Do you have any other idea what it could be?

Are you saying that with that change, it still gives the "outside machine limits" error? It doesn't on my bench system, when I use Z-1 where you have used Z-100. Did you allow the machine to restart after you saved this change to config.g?

3DRikat

@dc42 yes still the same error with either Z-1 or Z-100 and I restarted everytime I changed something in the config.g.

That is odd, the whole file works for me. Please try the following:

Send M208 without parameters, and check that the Z minimum is reported as -100 or whatever you have set it to.
Try entering the lines of your print one at a time into the GCode Console and see which one is failing.

M208
Axis limits X0.0:731.0, Y0.0:731.0, Z-1.0:108.0, U0.0:731.0, V0.0:731.0

Looks fine to me

dc42

In your M92 command you specified 200 steps/mm @ x16 microstepping. Is that correct?
If you send M92 without parameters, does it report that the Z steps/mm is 200?
If you use the jog buttons to jog Z up 5mm, does it rise the correct amount?

3DRikat

@dc42 said in Unable to run Gcodes from Estlcam in Web control:

Changed it to 400 steps/mm (T8 screw)

If you send M92 without parameters, does it report that the Z steps/mm is 200?

Steps/mm: X: 100.000, Y: 100.000, Z: 400.000, U: 100.000, V: 100.000, E: 420.000:420.000

If you use the jog buttons to jog Z up 5mm, does it rise the correct amount?

Yes, I measured the correct amount with my digital caliper. The difference is only 0,01mm.

radiomodell

@3DRikat Please try to use a work piece coordinate system. If you generated G-code with a Z-axis zero position at work piece upper surface, Z-axis will move outside machine limits when the tool dives into the material. Same can happen if your cad design touches X- or Y Axis zero in Estlcam and you add cutter radius compensation. Toolpath will be outside machine limits.

I used following G-code: G10 L2 P2 X5 Y5 Z25 to select 2nd coordinate system and activated it with G55.

3DRikat

@radiomodell I tryed it but it was just like before. After the outer square is done the Z axis rises and I have to stop it. There's the error message "outside machine limits".

I really don't know why the Z axis rises so high.
