General Mach Discussion / Re: Need help w/ taper milling

« on: January 22, 2011, 01:49:49 PM »

2 ways to do it IF it is a round hole.

1. Let a 3d cad/cam do all the work
2. Put new batteries in the calculator and work out the step over and diameters to do the radius. Start with milling a hole at the smallest diam all the way thru to the bottom. Then start working your way from the top to the bottom doing ever smaller spiral pockets. It is time consuming but can be done. You cna start with rough cutting with larger stepover then finish off with a really fine stepover to give a mooth finish.

IF you want them to act as limit switchs then you have to set them up as limit switches. In Config, portsand pins, inputs, assign the port and pin to the correct axis limit function.

Hope that helps, (;-) TP

It is in config, ports/pins, mill setup

Been there done that one as well,(;-) It does not hurt near  as bad after about the 3rd time you do it.

oK Next question when you did a voltage check on the power supply were you running ALL three drives at the same time you took the voltage reading??

IF you ran the 1024 screen and it did the same thing that would eliminate anything screen related and tends to point to an automated process still running.

Just a thought, (;-) TP

General Mach Discussion / Re: Can a slaved axis have different steps/mm in motor tuning

KEITH here is what you keep getting caught up in. YOU DON"T BUILD THE MACHINE THAT WAY.

You must build the machine to be accurate. IF not nothing in MACH is going to save you from yourself.

There is tuning in mach to compensate for manf tolerances (screw mapping and formulas) Yours is a design /build/ tolerance problem

It would be best to let the Gcode side drive that part and use Sheet Cam to post the code. At that point it is an automatic function.

Yes Jeff the idea is to get the BLOAT out of the install AND free up resources AND free up CPU time/interuptions.

It certainly does not mean you have to give up networking BUT for those that do not require it why not. If you feel it is not for you then please do not feel obligated to participate.

OK let's step back and start again.

IS this a laptop computer?

HOW are you determining that the XY are loosing steps?
