Been a long time since I was active on this forum, but it’s fabulous to come back after a year and have shiny new software to use! It’s awesome! Big thanks to the developers of WebControl.
Here’s my issue -
I’ve updated my original shield to run holey v51.28 and use aPi3b+ running WebControl 0.94 to drive it with a sled based on the meticulous Z-axis (8mm/rev screw w/ 1:1 ratio belt drive). The machine is much more accurate than my last runs in 2018, 2-3mm off over 80" and repeatability within a handful of thou (whisps of dust) when re-running text engraving gcode. Mechanically I’m quite happy with it.
However, there seems to be some instructions that aren’t executing in a run I was trying today. Here’s the segment of gcode:
(1001) (NO ARCS) (T1 D=0.25 CR=0 TAPER=30DEG - ZMIN=-0.025 - CHAMFER MILL) G0 G40 G90 G17 G20 (WHEN USING FUSION 360 FOR PERSONAL BLAH BLAH SUBSCRIPTION. ) (TRACE1 2) T1 M6 M3 S5000 G0 X2.6129 Y3.9257 G0 Z0.2197 G1 Z0.1 F20. G1 Z-0.020 G1 X2.6143 Y3.9275 G1 X2.6155 Y3.9291
It moves fine up till G1 Z-0.020 but it doesn’t enter the wood at this point. It just “air cuts” or barely skims the board depending on how the Z axis is zeroed. It just isn’t making this move. I’ve verified by gluing an indicator and mm scale on the axis carriage and there is just no movement, it goes up to Z0.2197 fine, and back to Z0.1, but won’t make this move.
I do have code that works:
(1001) (NO ARCS) (T1 D=0.25 CR=0 TAPER=30DEG - ZMIN=-0.025 - CHAMFER MILL) G0 G40 G90 G17 G20 (WHEN USING FUSION 360 FOR PERSONAL blah blah SUBSCRIPTION. ) (TRACE1 2) T1 M6 M3 S5000 G0 Z0.2197 G0 X2.6129 Y3.9257 G1 Z0.1 F20. G0 Z-0.020 G1 Z-0.020 G1 X2.6143 Y3.9275 G1 X2.6155 Y3.9291
If the Z move is duplicated with a G0 move, it runs fine. Why is it getting ignored?
At his point I’m leaning towards a speed issue - the Z move hasn’t completed before it starts the G1 X2.6143 Y3.9275.
This is a fusion 360 trace operation.
I’m thinking I’ll try makerverse 1.1.2 tomorrow to see if the same issue occurs there. (Had it installed earlier this week but i gave up because it was throwing all kinds of buffer overflow errors and giving weird speed responses to G2/G3 moves).
Thank you for any insight …
