Hello Guys, I almost have my 4×4 MPCNC ready.
Buy everything in the vicious store, I have a laptop with windows 10, I followed the instructions to the letter.
My problem lies in one of the Nema 17 engines of the Y axis. The movement of the shaft does not work, and probe changing the wiring for a new one that I buy here on the page …it only moves on the X axis
Did someone have a similar problem? It’s like the engine was dead.
something else, I have an LCD with card input, as I can add it to the board, so everything is handled from the controller and I do not use the PC.

What control board?
That is a different LCD you will need to edit the firmware to use it.November 20, 2017 at 2:14 am #48109
Hi Ryan , the board is RAMP 1.4 / DRV8825 drivers .November 20, 2017 at 6:31 am #48115
Did the other Y axis motor still work? Have you tried plugging it into another port, to see if it’s the drv8826 or the motor? Don’t swap the cables while it’s powered.November 20, 2017 at 7:31 pm #48159
Thank you very much, all the engines are running. I had to change one, it did not work.
My problem now arose with the Repetier-Host “, I charge the G code that I export using Estlcam \ V10, I give it to print and nothing happens.
The machine does not move, it connects but it does not move.
Connect it to the Estlcam and it works, it moves correctly.
but nothing happens with the Repetier

EstlCAM can’t connect to Marlin, so it sound like you programmed the Arduino with the EstlCAM software. You will either need to program the Arduino with the Marlin software or use EstlCAM to run the job. Repetier only connects to 3d printer software like Marlin.November 20, 2017 at 11:55 pm #48171Thanks for your time. Estlcam, I really like it is very intuitive and it looks very complete for the ability I have now.
Try all night to send a job from my PC to the Mpcnc using it … I could not … I do not see where it says to launch the work …I read all this post. Very good…

I’m following everything as it says, I do not know where I’m failing.

Now try as it says following all the steps, keep sending me the same ERROR.
However I could download and load the Marlin 1.6 without any problem, connect it to the repetier and send it a G file, it worked more or less well, it moves like a 3D printer, using the Z axis.

Not ug82…The one under it. Look at the steps one more time.November 24, 2017 at 4:52 pm #48422
Ok, thank you very much, I’m an idiot, i look, but I did not see.
Apologies. It’s working, now the problem I have is that I run out of space on the board as I can eliminate space or delete everything from the board in order to load what I’m missing
Attachments:November 24, 2017 at 5:03 pm #48424
Scroll up, that is then end of an error message, you have only used 40% of free mem. That is how it looks when it is successful. I don’t know what the error is. Have you tried it does it work?November 24, 2017 at 5:12 pm #48425
I go straight to the machine to test if it works
Attachments:November 24, 2017 at 5:42 pm #48427
already working and loading the codes, the problem I have now is that it moves from the work area, I travel from the center to a corner, and started working in that area.

Reset the arduino after you have placed the head and before you hit start.November 25, 2017 at 12:19 am #48441
I appreciate the time you take to respond.
I’m having the following problem, in Repetier, when I want to position my head, it just lets me move a few millimeters for one side, but then it does not let me return, or it just lets me return the same amount that I moved to the other side.
I can not use the entire space ….

I reloaded the firmware, but this time the, MPCNC813_GLCD_T8,
Something improved, I can control the machine.
My problem now is that the z axis, when moving does not rise, continues cutting until the drawing begins.
Following tutorials to see what I find …
I would like to know how to position a table and frame those measurements to cut inside it.

Be safe, use a pen not a power tool until the machine works as you expect.
To me it looks like you have CAM issues. Follow my tutorials and make sure everything works as it should. I include gcode to compare to. It should be identical. All cuts can be simulated with a pen, at the bare minimum use foam not wood, you are likely to break something this way.November 27, 2017 at 2:23 pm #48609
Are you running the T8 lead screw, or a threaded rod? Can’t tell for certain from the picture above, but if you are running the threaded rod with the T8 firmware, your steps/mm will be way off and the Z will likely look like it is not moving at all during a lift and cause the exact problem you are having with the bit dragging through the material instead of lifting and lowering to start the cut.November 28, 2017 at 11:14 am #48681
i buy everything on December 29, 2016 (vicious shop)
because labor issues this last month I could have more time and finish my MPCNC. I think my firmware is the old one, MPCNC813_GLCD , is the one that I just installed.
Apart from the repetier host, there is some more program
CAM, to control the machine, like the mach3.
now I will keep trying to make it work soon.November 28, 2017 at 11:30 am #48684
Stick to the recommended software until we get you working correctly. Try to go out on your own using other software will only frustrate you as I will not be able to help.November 29, 2017 at 9:41 am #48718
Vincent PollaroParticipantI think my firmware is the old one, MPCNC813_GLCD
OK. Be sure, as in your earlier post you said you installed the T8 firmware, which would cause the Z issue you described!I reloaded the firmware, but this time the, MPCNC813_GLCD_T8November 29, 2017 at 12:25 pm #48726
Sorry, copy and paste problems.
What I meant was that my Firmware was the new one for the T8 screw.
But in reality, the one I need is the old for my “5/16″ Leadscrew ”
Which I already have installed and running, fix the problem.
Now I’m focusing on fixing the cables a bit and improving the aesthetics of my machine.

In shortly i will upload a copy of my G code for a file I want to try to run.November 29, 2017 at 1:16 pm #48731
ok, this is the file I’m trying to recreate, design and export from Corel in DXF. 30 x 30 centimeters.
Here is the G-Code
Attachments:November 29, 2017 at 1:41 pm #48734
I placed the sharpie’s point, right where the purple X is, once started it moved to a corner, then it came back and started to run.

How did you make the gcode? The problem is definitely in the gcode.
G00 X0.0000 Y0.0000 Z0.0000 G00 Z1.5000 ;No. 1: Engraving 2 G00 X482.7307 Y453.1098
You’ve got your origin set to the lower left corner, and you’re drawing way over at 482,453.
The process I normally take (and I assumed you were taking, because it’s pretty common) is:
1) Make the lower left corner of the thing you’re drawing 0,0 in CAM
2) Go to the place on the workpiece (in this case the paper) where you want the lower left corner
3) Reset the home offsets (or just power cycle the arduino) to make the current location 0,0,0 in the firmware
4) print/run gcode
If you want to do it they way you are (where the gcode defines where in your CNC workspace the paper is) then just remove the line
G00 X0.0000 Y0.0000 Z0.0000from the gcode.
The reason you would want to draw at 0,0,0 and reset the origin while at your workpiece is that it’s much easier to locate the paper in your workspace.November 29, 2017 at 4:40 pm #48741
Thank you very much for the help of all, it is already working correctly.
I have a small Z problem but it is because of the bed or the legs of the machine.
But it works. 🙂
During the test, i design a sharpie mount that is a bit more easy to use and put on.
It goes on top of the “Ryan” Dewalt Mount 660.
Thanks everyone for your help !!!!
shortly I will continue bothering haha ..
