Spindle does not start and mapping does not work #50
Comments
Hi, can you make sure that every file contains an 'M3' statement to turn on the spindle? You may want to add a delay statement 'G4 P5' after 'M3' so you can stop the job should M3 not turn on the spindle. This shouldn't be a problem with OpenCNCPilot. Concerning your other issue: did you change the origin between probing/apply height map and etching? is your cutting depth set deep enough in pcb-gcode? Martin |
Hi Martin, thanks for the reply. About the probing: I don't think I changed the origin because I usually run the probing and apply the height map as soon as it finishes. The depth should be okay because it used to work fine. |
Hi Giorgio, |
Hi deHarro, |
Hi Giorgio, |
Oh cool!! I will buy some of these. |
So do I, sorry :( |
Are you not zeroing the Z axis? I usually zero the Z axis and then start the probing from where, so I have a reference point I can refer to, when I change things. Regarding the spindle not starting: Is everything connected properly? It seems like the electrical connection, which tells the spindle to start is broken and prevents the signal to get through... |
The spindle is connected properly because if I write the manual command S1000 the spindle starts spinning. |
Ok so why don't you open the gcode file with a text editor (notepad should be fine, just right click the gcode file and select "open with") , replace "M3" with "M3 S1000" and try again? You can zero the Z axis, by bringing your spindle above the origin point you want to set, connecting the probe to the copper clad and the spindle bit, and pressing the "zero Z" button under the "Macros" tab. I would also suggest you do a "G92X0Y0Z0" just to be 100% sure that your origin point is properly set. After that you can create a new probing area, probe it out, disconnect the probe from the spindle bit and the copper clad, apply the height map and start the routing job. |
Thanks sirsenor, you have Bern really clear! Today I try and I will let you know. |
So, I fixed the problem of the spindle, somehow the default velocity is set to zero. |
I am using -0.05mm |
I use -0.1

I am using-1.12 but stil does not work properly. I was wondering: Once i press “ applyheightmap” shockerà I see mi circuitboard in black on the probed surface? Because I still see only the colored surfaced which indicates the height. |
1mm is way too much, there is no way that it doesn't cut through the copper (and half the substrate) at that depth! |
I miss spelled, i use -0.12. |
I still haven’t done the video because I did not have time. I was trying to chance some settima and non i get this message when I open the gcode: “Could not parse GCode File, no preview/editing available rum this file at your own risk. When I simplify the GCode I only obtain a line of code. |
there is a problem in line 3523, specifically a word beside XYZIJK comes after a G%% motion command which is not allowed. This means that OpenCNCPilot could not convert it into it's internal represenation, so you can't use simplify/anything |
So here it is the video :https://we.tl/DKroBFKHwl I have used -0.17 for the depth of cut but the spindle tears apart the board. |
Sorry, I won't download a 700MB rar for a video. please post it on a video hosting platform like YouTube or vimeo |
Ok so Ive watched the first 2 minutes of the video and right off the bat I see a huge difference to my machine (I have the same machine). Your stepper motors seem to be accelerating too slow and that might cause the Z motor to never reach the correct Z height in time. Could you screenshot the window that opens when you press the "GRBL settings" button? Try raising the acceleration speed of the motors ( I believe mine are set too 800mm/s²) and try to probe/route something again. |
Here it is the youtube link of the video. Soon I will post the photo of the grlb settings. |
Yes this looks a lot better. I would suggest you try to route something with a depth of -0.05mm. I am using the standard chinese routing bits you get from amazon/ebay/aliexpress (0.1mm and 10°) |
Thanks a lot. I will try with 0.05. |
well you have to keep in mind that these tips are only made for engraving very small depths and not 0.1mm :D |
well...first I would do a height test...placing any thin object over the
table and then lowering step by step z axix untill the bit touches gentle
the surface of that object...then reset z...command z for + 30 and command
z to zero and check if the bit is still touching the object as itvwas in
the beginning...try several times...I had this problem where z axis was
mechanically with malfunction.

I finally got really good results . |
You could just edit the .gcode file to that. Image your board has the dimensions 20x30mm. You just have to copy the entire .gcode file contents, append "G0X21Y0" (or something similiar) followed by "G92X0Y0", paste the .gcode you just copied, load it into OpenCNCPilot and start probing/routing. |
Hi Giorgio, what did you change to get better results? was your origin incorrect? Cheers! |
The problem I think it was to due to the settimg of the grlb settimgs, once I have set $120,$121 and $122 to 600 and set the depth to 0.06 as sirsenor everything worked perfectly! I still add manually M3 S1000 to start the spindle! |
Ok. |
Hi Martin,
you tool is wonderful, makes my little Chinese cnc work as a good cnc =)
It has been a couple week since I am having some troubles though.
The spindle sometimes start to spin and sometimes does not and these cause the tip to break.
I wonder If it is a problem of the setting of the software or I do something wrong with the .ulp pcb-gcode-setup on Eagle.
Another problem I am facing these last weeks is that even if I click on apply height map the tip does not etch because it is too far up with respect to the copper.
I hope you can help me.
I am running the software on windows and I have Grbl1.1
Thanks
