General Mach Discussion / Very slow jog
« on: November 29, 2008, 03:57:51 PM »
I've done something wrong or inadvertently reset something, but I just can’t figure out what it is. Everything was running fine until I tried to jog to a new position. The machine jogs so slow it's painful. Actual cutting is no problem and it appears to run as normal. The jog rate is set to 100%. I have increased Vel and Acc, the pulse rates and debounce to no avail. I have tried it in both inches and metric, the same.

I'm at a lose to think of anything else at the moment, perhaps someone could help me out with this please.

Thanks Tony

I made a few test cuts today and all appear to be working fine. Dimensions are more accurate with steps per,  set at 1511 rater than 1600.  :)

When I entered your first number 151. and  I would get a 2mm move with G0x2 and the decimal point was one out in the wizard inputs to get the correct cut ie 200 to get 20mm cut.

The leadscrew is 6mm so I have entered 1600 in the steps per. Now I get an accurate result in the wizard and the G0X2 moves 2mm still.

Does all appear to be correct now. 8)

I suppose your'e right.  I had to try it. Unfortunately I coudn't start the spindle (noise). It appears to be more accurate ie it moves 25mm at G0X2.

Arrhh I didn't see those last few posts. I was going to say that I had to add an extra 0 (200) to the wizards input to get a 20mm circle. Has that anything to do with your typo.
