General Mach Discussion / Some advice needed on Motion Control and Drivers
« on: August 09, 2017, 01:25:07 PM »
Hello everyone,
First time posting, since I have only used open source software on my CNC's so far, but am now ready to upgrade to Mach3.
My current setup works relatively ok, but I dont trust my electronics (Arduino Grbl + gshield). The arduino inputs are too unstable and it keeps reporting a trigger of the mechanical switches when they are not being pressed.
So, I will invest some money and ditch the arduino+gshield+UGCS software. To replace them, I will buy Mach3 and electonics wich work with both the software and my current steppers (Nema 23/17). I live in Portugal, so my buying options are limited to EU stores, as buying from USA will probably double whatever price I can get because of the import taxes. Here are a couple of options I have found:
Finally, is there anything that Im doing wrong? Do you have any suggestions as to what I should buy in terms of hardware? I have spent some time on Ebay, but buying chinese products seems a risk not worth taking, i want some support in case the components fail.
Thanks in advance for the replys!

Here are a couple of options I have found:
- A motion control board, with integrated drivers from CNC Robotica, a spanish store (http://cnc-robotica.com/es/interfaces/131-interface-drivers-4-ejes-usb-45-amp.html). Although this option may bring the same problems I had with the Arduino, because its a All-in-one, this board seems way more robust than what I have now, and it works on 24V, which has less problems in terms of noise problems. Is this + mach3 enough to run my CNC?
- A BOB+Motion controller + External drivers from Prizma (http://www.prizma.rs/ml/index.php/motion-controls/motion-controllers-and-breakout-boards/usb-mc). This requires me to purchase 5 separate hardware components (1 BOB + 1 MC + 3 Drivers) and it will be a bit more expensive (325€ vs 500€). Is it worth it? What do I gain from this configuration?
Finally, is there anything that Im doing wrong? Do you have any suggestions as to what I should buy in terms of hardware? I have spent some time on Ebay, but buying chinese products seems a risk not worth taking, i want some support in case the components fail.
