VCarve Desktop Problem

How do I know the type of CNC machine i have being that its home built I see people saying they have this type or that type , is that according to the post processor that supports the built machine , and if so how would i know the type of machine I have , I have just purchased V Carve Desktop and when i send a job to be milled it doesn't work regardless if it in inches or in milometers , I up dated Grbl and also Arduino software so I cant figure out why its not working any help would be appreciated

Tech support at Vectric says to use the Grbl Inch post processor but as I understand Grbl uses mm so that would be just one giant mess using inches But I tried it any who and ended up with the same result , it didnt work .The most wacky thing is that when I used the trial software everything worked that one reason why I bought it , I tried different typs of post processors within the VCarve software and nothings seems to work . The CNC Machine was working with sketchucam and sketchup and open builds but now with the purchased version of vCarve any ideas ? :slight_smile:

Maybe there are CNC Facebook Groups with Arduino that can help you in a more gear-oriented manner.

Usually the CNC needs to be configured so that the motors can operate according to the assembly that was made, how many motor steps for a certain amount of space advance, and you need to consider each part that was used in the project. Usually people do a domestic assembly based on a project that has been completely described, from the mechanical part to the software part. Here's an example:

When the building and the flashing is done, it's time to do something! Download the Universal G-Code Sender

Since the CNC accepts the G-code file, this may help:

vCarve - convert 3D models into gCode for CNC Router

GRBL can be set to accept metric or imperial measurements. ( See $13 in the parameters )

But regardless of that you should see some movement if you pre processor was correct.
I set mine to MACH2 or MACH3 and have never had any issues.

You also need to set the stepping correctly in GRBL too.
That depends on the lead screws pitch and the motor type.

If you are using NEMA 17 the majority use 200 steps. (ignore any micro stepping jumpers you ma have)

Take note of the firmware settings of GRBL from $100 onwards.
