Controller Replacement BlackBox

Post by gdon_2003 »

I was on the https://openbuildspartstore.com/ site and they have a new controller called BlackBox. Has anyone looked at this and think it may be a viable replacement for the NWA controller. The BlackBox supports limit switches and more. Do you think it would work on a Shark Pro Plus HD?
Thanks

Should work as long as your stepper motors are 4 wire. You will also need a control software such as Mach3.

Can you please explain why you think you need Mach 3/4 software. The openbuilds CONTROL software is free and is supposed to run your cnc router. If you are using CAM/CAD software like you do now and then use the NWA Control panel to load your gcode files how is the blackbox different and needing Mach 3/4?

Thanks

This looks interesting as a possible replacement. It runs on GRBL, so won't allow the use of Mach3/4, but instead OpenBuild's own software (as you've mentioned). One downside is it doesn't appear to have any support for a pendant (dedicated pendant, or Xbox controller as many use with Mach). That's unfortunate, as that is an easy way to control the machine that many of us like. The Shark Pro's do use a 4-wire stepper (Nema 23, bipolar 269 oz-in, 1.8 degree/200 step) so would simply be a matter of cutting off the NWA DB9 end, and wiring directly and correctly. I believe these steppers are around 3V / 1.8A/phase, but not absolutely sure.

So just looking at the Blackbox it would seem to work if you really wanted it to. My concern is about propriety systems like NWA. If NWA went away then the license files needed to run their controller could not be generated and your controller would become a brick. I do not think NWA is going away but I came from an open source background and like the freedom of not being tied to an OEM propriety software hardware platform. I saw many customers of mine get stranded when their vendor went out of business or quit supporting their product. For now I will be keeping the OEM controller but will keep my eye out for the future. The Blackbox does support some pendants but I do not know if the newer HD4 and Piriania pendants would work. There may be other pendants that would.

So for now the discussion is academic for me but you never know when you need to make changes. Fore warned is fore armed.

I like the idea of a backup system. I don't use my machine commercially, so if New Wave ever did go down without publishing license files (a little unlikely, since they'd more likely be bought out if they went under), I could live for a couple weeks without using the CNC machine. During that time, I'd imagine this group would quickly devise a workaround.

With a little looking it didn't take long to get my Shark HD4 up on a Blackbox controller.
A few tuning parameters in grbl and I had the Blackbox controller cutting the same circles I cut with the Shark controller/pendant.

Do I plan on keeping the Blackbox connected, not at this time, it's for another project

recently purchased a BlackBox Controller and set it up on a dummy station. Runs well and other than no being able to run the A Axis on a separate control channel (you need to switch cable) it has feature that I like.

1. I can control my spindle speed from within the Tap file.

2. I can turn my Spindle and the water pump on and off from the Tap file

3. Limit switches, no more running past the machine boundaries when you make a mistake.

4. Macros, You can program actions to take on command. Move to a tool change area, move the tool head to a distant part of the machine away from the work, and so on.

Haven't hooked it up the the Shark yet because I'm in the middle of a large project. but will soon..

Has anyone successfully removed and replaced the NWA controller with the Openbuilds Blackbox? Now that there is a pendant available for the Blackbox it looks like a viable option. I am tossing around the idea of completely gutting the Shark electronics, motors and pendant and replacing it with the OpenBuilds Blackbox, motors, pendant and adding limit switches. From what I see this might be a better way to go to get away from NWA's proprietary system and software. I really like the fact that I would be able to use LightBurn software with the laser.

Any thoughts - has anyone gone this route?
