General Mach Discussion / Re: Rotational milling speed?

« on: December 20, 2006, 07:16:12 PM »

Hi JQ,
    First, I'm running version 2.0.028. This is what I found. Your xml did not have the use diameter for feed rate checked. I ran your test file with this unchecked. The 4th axis was reading 17.1375 at 2:19 minutes into the cycle. With it checked, the 4th axis was reading 19.2750 0:04 into the cycle  . Try to change this setting, close Mach. Open Mach back up and see if the change stayed and try to run your file again.

JQ,
   I forgot to ask, what version of Mach are you using? Mach 3 version 2.0.0?? Also, can you post the Gcode file that is running slow for you.

Step is 80 per degree? I will look at the xml once it is posted.

Hi JQ,
    What are your 4th axis settings in motor tuning? I haven't got to mess with this yet, but hope to one day. Can you post your xml. file for us to look at?

Your welcome Terry,
   No, on the steps, they will actually double. Set it to 6400 per for 1 inch of movement. If you set it to 1 full step you will have a resolution of .0003125. At 1/2 step it will give you a resolution of .00015625.

If your gearing is one to one and your not micro stepping it will go like this.
16 tpi = 16 rounds per inch
200 steps per rev. = 200 X 16 = 3200 per inch.

Very Nice Ian.  :)Merry Christmas. This subject will most likely be moved to the design exchange. I think it should be put up on the general board for a while though.

Weird indeed. I know you have tried, but you really need to find something in commmon with the problem. Cables, motors, board. Sounds like you have tried this and moved the problem. Try the steps you mentioned again and see what happens the second go round. Hey, maybe you can chase the problem right off of the board. I will help all I can.
