G-Code, CAD, and CAM discussions / Re: recently putchased bobcad post help please

« on: March 13, 2015, 06:59:42 AM »

If you contact BobCad they can supply you with their Mach3 post-processor and they will also be able to answer any other questions you may have.

I appreciate that this is not directly answering your post but I think it is better if you get the information you require direct from the horse's mouth (so to speak).

Mach4 General Discussion / Re: Why does the roadrunner.tap have an M99 at the end?

« on: March 13, 2015, 03:27:52 AM »

I think it was used as a Demo at events promoting Mach4 so it was convenient to have it re-run in an endless loop.

General Mach Discussion / Re: OEM codes for buttons, DRO's and LED's

« on: March 13, 2015, 02:36:12 AM »

I am coming up with an intermittant problem where the program stops running and it comes up with message "radius to end of arc differs from radius to start" I know the file is ok as I have already cut this file on the large machine. Why would this be coming up especially when I could run this file again and it wouldn't faulter. It also does it with other files as well

Some versions of Mach3 are more tolerant than others with regard to this intermittent problem (load the file first time,it fails - load it a second time and it is OK).
It is worth checking that you have the correct IJ Mode set in Config / General Config and perhaps as a general rule ensure that it is defined at the start of all your Gcode files with G90.1 or G91.1 as appropriate for the way in which arcs have been created in your CAD / CAM.

I wish you every success Brian that badge certainly looks great - my wife won't let me loose on a bike again but perhaps one day, when I get old enough, it will be a new Harley.

Excellent work my friend - are you going to be making some more for the other Welsh BMW riders ?

FAQs / Re: Proxxon FF500 cnc setup for Mach3 help

« on: March 11, 2015, 03:23:11 AM »

I may be wrong but it is my understanding that the FF500 controller uses RS232 serial communication with the PC. That being the case it would probably be easier to just substitute the controller with one that has either Parallel port, USB or ethernet communication with the PC. Please be aware that some of the Chinese 'all in one' controller boards are dire but others can perform extremely well (some internet research before purchase may be good).

Hope this helps.

Mach4 General Discussion / Re: USB Smooth Stepper & Mach 4

« on: March 11, 2015, 02:34:56 AM »

Great news Bill - when you get the time please start a new thread and post your experience on setting-up and using the PMDX with Mach4 - this will no doubt be of interest to many others that follow.

General Mach Discussion / Re: AC dimmer via Mach3

« on: March 10, 2015, 03:27:13 AM »

Check out  SSR's (Solid State Relays) - many types are 'opto-isolated', require less than 10mA drive current and can be driven directly from the Mach3 PWM signal (spindle control) and will switch a/c mains voltages proportionally with the PWM waveform. As they switch at the 'zero crossing point' of the mains a/c there is little or no EMI noise produced by their operation and this may offer a solution.
