  • 6 Axis CNC MACH3 Engraving Machine Interface Breakout Board USB PWM Spindle with ASKPOWER A131 Series

    In short; it shouldn't be a problem.You need to pick motor driver as the board controls the driver and driver controls motor. The board sends direction and step pulses to driver (i would say this is standard for all driver boards), so you have two connections there. And motors are 4 cables bipolar and 8 cables unipolar both can be connected in bipolar setup. Just check the driver, it should have 4 connection A+ A- and B+ B- for the two motor coils.

    i tested it and sure you can disable it. i will change this in the instructabe so i dont confuse anyone.

    I will need to test this to be 100% sure abut why i set it, but you are right i didnt needed the output1 as the pwm signal is set in Config / Ports&pins / motor outputs / Spindle.

    Very interesting. I am really starting to wonder what the plasma i ordered will do :D. I really hope it is ok to post a link so you can have a look. their HF plasmas are 3phase. I have single phase and it is touch start and it is Pilot Arc. http://www.telwin.com/webtelwin/site.nsf/webindex?... So what you recon? without HF what would be the distance it would be able to strike proper arc? In my view you have high voltage charged electrode which ionizes air so creating conductive path for the arc thats why i thought 5mm isnt totally impossible, but yeah... maybe not too real either. I will share my experience once ill try the machine out. thanks for your answers

    SiThanks for the replay and important info. I for example didnt realized about RFI. And i should have mention that even the plasma i bought is "touch start" it does have pilot arc so it will cut mesh or rusty material. (not sure if i can post here link to the shop so i rather didnt) Basically from my research HF is to create the initial spark, touch cant do that. You need to (touch) or in case of my machine according to manufacturer be less than 5mm from material. So if i understand all i am risking here is that the initial start will not work? Also cutting on pilot arc doesnt really make a sense to me as it wouldn't cut the material with same power so you might not cut trough or cut will be uneven. So i see little difference between not cut material or cut badly (on pilot arc...see more »SiThanks for the replay and important info. I for example didnt realized about RFI.

Bare in mind I dont own yet any plasma so; no experience :D. Thanks for all infoThanksVlad

    HiIn text is written: The cutter must have 'HF Start'. I wonder why is that? I was ordering plasma for my machine recently and it is not HF and according to manufacturer the torch just needs to be close enough and the arch will strike, similar to use with roller guide wheel. So why it wouldn't work on your machine and why it is must have? the HF creates strong interference with electronics if cheap machine bought, so bigger problem would be using HF.
