CandCNC thc and rotary axis
Posted: Fri Aug 18, 2017 10:39 am
Hi All
Having some issues getting my rotary axis setup correctly, I have a CandCNC BladeRunner Dragon Cut 620-5 control system, if i utilise the post HTHCII-DTHCIVRotaryPipeFit-setacis_REV3 there are a few issues:
1) as soon as I load the gcode it pops up that the pipe od has been set for 1 inch (my machine is all setup in metric) and also the file was draw and setup in sheetcam for 76mm tube.
2)It then automatically sets the steps and speed of the axis (i assume to accommodate 1 inch tube not the 76)
3) if i do dry run the file it is moving along my Y axis instead of X axis as the length of the tube.
If i use the normal mach3 rotary post then there is no auto setting of the steps etc so it keeps what i have put and motion appears mostly correct with some strange slowdown and jumpy movement on the sides of circles otherwise it mostly runs correctly. problem being it then doesn't include any of the THC commands or control.
On a side note if i try the screen set for rotary that came with the candcnc system it has a "test 1 revolution button" along with some settings etc, if i set 2000 steps with a 1:3 gear reduction (which is what i have) and click test it does spin 1 revolution (50% at full speed and 50 at a reduced speed) but if i look at the dro it only reads 36 (not 360) if i then change it to 200 steps (as if no micro stepping) then the test button doesn't spin it a full revolution yet typing G0 B360 does spin 1 revolution.
Thanks
