Hi all ,
I am looking for some advice from the technically advanced here. I have a CNC Shark Pro from Next Wave Automation. The machine has been awesome. Recently I replaced the stepper motors and the direction of travel was reversed on all of them. I took some bad advice and switched some wires to reverse it and fried the driver board. I've since learned you can make the changes in the software. Problem is the driver board is no longer made so I have to replace it with something different. Wondering if anyone can recommend one? 3 axis, power supply is 24V 6.5amp. I'm not an electronics guy, just a simple cabinetmaker but I really miss this machine, it has served me so well for the past 3 years. Any help or recommendations would be greatly appreciated. Thanks in advance

Re: Stepper Driver Board
If it's just got three stepper motors, one on each axis there are lots of controllers that will work. An inexpensive solution that will probably work is the OpebBuilds Black Box32:

Just make sure you check with OpenBuilds first to see if it will support the stepper motors you installed. You will have to set up the box to properly represent that ratios between the motors and the distance traveled, but that should not be hard. There are lots of other choices but I've used that one on a small 3D machine I built and it worked perfectly. No clue how it would interface to a VFD iv you can control the spindle speed in software, but they will certainly know those answers.
And there are a number of other choices if you do a search on the web or I would think the modern control box from Shark should adapt to your machine.
If you have 4 wire steppers you need to just reverse one of the two pairs to reverse the direction. Also, you probably only took out the final stage driver and that should be fixable bu someone with the proper tools and knowledge.
