Config menu then Motor Tuning and the steps per unit for the A Axis would be  11.111111111

How that is worked out is gear ratio is 36/18 = 2 . So stepper being 200 steps per rev and geckos having 10 microsteps it would be 2 x 200 x 10 = 4000steps per rev. 1 Rev is 360 degrees so 4000/360 = 11.111111111 steps per degree.

ok tried that but still moving very slowly, barely turning in the a axis & only cutting it round very very slowly? maybe i need to change some other settings? im going to send a gcode i use for this & maybe then u can help figure out my problems! but im going to send to your email, since it took me so long to get it created, dont really want to post it on here? thanx r neely!

Try increasing the Velocity for the A Axis in motor tuning, it is likely very slow. Also are your X Y and Z steps per unit set correctly? ie if you command a move of 1 inch on each axis do they move that distance.

hey im not sure how to check if the motors move 1 inch? tried to set my a axis faster but my x axis is still barely moving when i try to run my spiral or the 2nd code i sent you. but when i run the 1st 6 sided code the x axis works fine but when it comes back t 0, the a axis just spins! i obviously dont have my settings right but not sure how to fix them? ron did you get my gcodes, & my xml files? can you tell anything from them what i need to set my motors to? thanx ron

To test your axis you need to measure. For example  you can zero the X DRO in Mach then go to MDI page and  comand a moveof say G0X1 and the X should move 1 inch, the same procedure for other axis.
You will likely also have to set a rotational radius for the A Axis on the settings page. I think your code shows the surface of the pens as Z Zero so looks to me like you will have to set the radius as whatever your pens are.
Your A Axis velocity will be in degrees per minute so if it was set to 360 that would mean it only turns 1 revolution in one minute so you need it a lot higher than that. How high you can go depends on your motor but test out from motor tuning page by increasing in steps and using the up arrow key and keep increasing until you hear it stall then back off a bit.
