I have a smaller Maslow than standard, and I have a scrap piece of plywood which is even smaller than by frame. I’m trying to cut the test cuts to finish calibration but they are always off the edge of my plywood.
Where does the test cut occur? What is it’s origin, and how can I move it to the position I want?
The little diagram in the calibration page doesn’t seem to tell me where the cut will start, it doesn’t seem to be referenced to either the home position or the current router position.
Alternatively, where are the calibration values stored, and can I update hem manually and use a simple gcode file for the test cut, which I can then place wherever I need to.
From the Home position (0,0) the router moves northwest to -300, 300 then east to 300, 300 then south to 300, -300 cutting at each location. It then travels west to -300, -300 and waits for the next command, either finished or re-cut. For re-cut it moves back to 0, 0 plus (minus?) a 20mm? offset and repeats. It uses relative coordinates for the pattern.
The routine is found in GroundControl/UIElements/measureMachinePopup.py
Yes, I’ve just looked at that. So if I change the home position then the test pattern should change? That didn’t seem to be happening for me this morning.
I may alter the code and see if I can get a test pattern.
I think that the start position is hard-coded. You could edit measureMachinePopup.py, I think. Be aware of absolute and relative coordinates.
That’s an interesting issue. I wonder whether we should put something in the Advanced settings to allow changing the size of the pattern for smaller work areas.
Were you able to get the cuts to work?
Is agree that making the test pattern adaptable might be better. Great suggestion @blurfl!
I’m in the UK, so won’t get to try anything until tomorrow morning.
The sled seemed to go outside the boundaries of the workpiece area I had set as well, which surprised me. Perhaps the test cut should be some proportion of the work area.
That makes sense.
Out of curiosity, what size is your work area?
About 860mm x 730mm. The fram eis bigger, but that’s the size of the scrap plywood I had.
If you change the position that the cut is made, you change the calibration

Hmm, itlooks like my home positionisn’t at 0,0. I think that may be why I have such a problem with the test cut. It’s at 565,391. As the test cut is at 0,0 this gives me a huge offset for the test cut.
This is after define home/goto home:
The settings are here:
The frame (with sled at home position is here:
The sled is at the home position, so after setting home, should the red marker jump to the centre of the workpiece? Or does it stay at a position within the workpiece?
It’s here after define home:
The cal wants to begin from a position which is half way between the two motors and centered in the workarea vertically below the motor height offset. I don’t think that it will work from a shifted home position.
