We were evaluating the TinyG V7 with Firmware version 0.94 and have come across some weird behavior in following case:
We wanted to use X and Z axis and Y axis is disabled. Axis parameters are properly configured and single axis motion happens properly.
But for below case, some bug is observed.
1. Start the TinyG
2. Get the machine to X30.707 and Z50.727 using command: G1X30.707Z50.727F500
3. Now we want to generate a ARC motion with Radius 25mm using command: G18 G02X67.738Z23.617R25F250
On giving above command, the machine traces half arc properly, but then suddenly starts putting steps in Y axis and takes the Z to zero position and Y to 23.617 mm position.
This happen to be a bug with ARC motion commands in XZ plane.
Kindly look into this and provide a fix for the same.
