Glad you got it fixed Nathan.

You need to pause the macro to give Mach time to catch up.

Try this:-

While IsMoving()

FAQs / Re: PCB Boards

Hi Hollydog,

Yes, it is pretty easy to do it this way provided you can accept 'isolation routing' for the finished PCB.
Rather than explain the whole process here, this is a link to the way I have done it  http://www.cooperman.talktalk.net/files/15.htm

If you need to remove all, or just some of the unwanted copper then a program such as CopperCAM could produce the toolpath but this route produces a large GCode file with even larger machining times involved.

General Mach Discussion / Re: Shop Sabre Mach3 Set Up

Hi Bill,

Ignore my previous ramblings - I have just been informed that the 2 Shop Sabre machines I was involved with the relocation of each had the WinCNC controller boards fitted as standard. 
So it should just be a case of downloading the manual, identifying the step and direction and limit switch pin connections etc and configuring Mach to supply the pulses.

No not necessarily - If the machine is genuinely configured to run from WinCNC (which would indicate that it may have already been modified), then WinCNC outputs step and direction signals to drive the machine in a similar way to Mach. Thus with a bit of sorting the pin allocations and timing it should be capable of running with Mach.

Hi Bill,

Generally the Shop Sabre machines have their own motion controller built-in and so Mach is not required for their operation. If you plan on stripping out the electronics and rewiring it then use axis controllers which accept step and direction signals to achieve Mach compatability.

With regard to your limit switches - It is better to run two wires because the machine frame is not always all at the same potential (moving axis for example may only be electrically connected to the main frame via the slides bearings). Also ground loops are a potential source of noise pickup and subsequent problems. Don't forget to used screened cable (grounded at the controller end only, preferable to a single point ground connection).

Welcome to the forum Luis.

Looking at your excellent work I think we will all be learning a lot about art from you. In return, the forum hosts many skills in CNC and any problems with your machines or software you post here are sure to be resolved quickly.

No problem Sir - my pleasure.

Glad you liked the website. I must get on with the laser project now the weather has turned for the better and I don't freeze in the workshop.
