You losing steps at 10mm per minute?

[Martin ConnellyParticipant @martinconnelly55370]

At 10mm/min feed you are rubbing not cutting. Something around 200mm/min would be more typical for this combination of tool and material. Does your version of Mach3 have the feeds and speeds wizard? If so use it to ensure you are cutting not rubbing. Load on stepper motors will increase if you try to push a rubbing tool into the work piece.

Thanks everyone I will try in morning 10mm/min was to try & see what is happening but 200mm/min too much for this m/c there was no load whilst cutting as DOC was 0.2mm to see what shape was being produced not sure about losing steps as my job was programming & machining 1st article any fault I was back programming & maintenance took over m/c until fixed

If the computer on which Mach3 is installed is not up to spec, then the pulse stream will not be consitant enough for smooth movement – to the point of missing steps. Laptops are not generally considered to be suitable for use with Mach3 to drive a machine.

Acceleration settings within Mach3 must be appropriate and also be sure the machine axes aren't binding.

Barrie just tried the 100mm square as soon as it started moving in Y m/c was making a horrendous noise and eventually stopped on the 4th side heading Y+ about 3/4 way up from comments this noise it is making is it losing steps? Martin didn't get a chance to try your prog yet computer is Acer Aspire with Windows XP bought 2nd hand for the job no wifi or internet the only thing loaded is cad/cam & Mach3. Any ideas on what to do next appreciated
Many thanks Ray

Could swap over the X & Y wires from the steppers which would totally eliminate any code or software issues.

A video of the machine playing up could be helpful.

The whole setup needs to be fairly close to ideal for reliable running, so step duration, acceleration, max step rate and some other settings should be well chosen to try to avoid problems.

It seems you are using a laptop which may be contributing to the problem. To check for compatibility with Mach3 be sure to run the DriverTest program contained in the Mach3 folder.
