Hello,
I recently finished building aN Ox CNC router. I am using the tiny g v8 with firm ware 4.40.
400 w spindle.
I followed the tiny g wiki during set up. The router works fine in most respects.
I am having difficulties in three areas;
- I can not get my limit switches working properly.
X is set min to home and limit. Max X is set to limit only. Same for Y axis. The reverse for Z.
The tiny g freezes when it activates the X min. Acts as limit only. I have tried various latch and back off values to no avail. I have also tried different settings for search velocity etc.
Z seems to function.
- When I run the following g code for a 100mm by 100 mm square, the g code stops in the far corner of the square then skips to the end of the g code. Retracts in z then turns off spindle. Seems as if it is skipping lines.
G90 G21
G01 z5. F75.
G01 z-5 f75.
G01 f600
y100
X100
-y100
-x100
G01 z5 f75.
M5
M30
This runs fine in the chilipeppr simulation.
- I was not able to get homing to work ( even with switches set to min home only) . So I tried jogging spindle to a position that I desired and then set machine zero. I then jogged over to work piece and set g54 zero for my program. The problem is that if I click on return to machine zero, it will occasionally go to some random spot not my assigned g53 machine zero. Is my tiny g just losing connection during these moves?
Any help would be greatly appreciated!
Best regards
Steve
