General Mach Discussion / Re: Foam cutter with 4 independent of each other?

Thanks kf2qd,
I do not total understand " Functin Cfg menu and select formulas and in the A line put X and in the B line put Y. The AB stage will copy the motion of the XY stage. If you want some other ratio (AB end 3/4 of the XY end  then you would put x*.75 in the A line and y*.75 for B)" but will soon.
 I am not up and running yet, but as soon as I get my motion control board back I will verify if a g-code file manipulated in Excel will still work in Mach3.
If it OK with you, may I contact you direct?

Ok ... For example, I want to cut a tapered column or a column with one end being square. I want the flexibility to duplicate anything.

Thanks Hood -your input puts me that much closer- I will crack this nut

I missed the AXIS in my title. The answer is yes to independent travel, one solution is to run two complete units and play with steps per inch or insert G4 (Dwell) in the G-code script. But other than that you are saying, the feedrate stays consistant between the towers? Is it possible to play with the G-code lines to slow one tower?
Thanks Again

General Mach Discussion / Re: Parallel Port Voltage

Hi, just along shot but a circuit with little or no current will display  potential voltage, as soon as current increase the voltage drops , very similar to pinching a garden hose with the tap slightly open. Will spray a single blast but reduces to a dribble. Check the power supply voltage with current flow for a true voltage output. Hope that puts you on the path.

General Mach Discussion / Foam cutter with 4 independent of each other?

« on: September 18, 2010, 06:53:31 PM »

Hello, I am in the process of assembling a hotwire machine, and would like advise on controlling 4 independent of each other, I have download one screenset but I am unable to get it to function. I have imported a DXF file into Mach3 and then stripped the TAP file in Word and then analyze it in EXECL. Found a lot of miss direction in directional control. Any help would appreciated.
Thanks Les
