Twin screws on the Joes 2006?

[IBBruin]

I can't say I've read everything there is to read on the Joe's 2006 machine but I've read a bunch. How does this machine perform overall? I'm concerned about the single motor moving the gantry weight. Would it be any benefit to modify it using two motors/screws to move the gantry? I've already started cutting some of the pieces to make one and I'm learning the hard way about an underpowered machine.

The one I have now does good for light duty work but is having a hard time dealing with repeated and prolonged MDF cuts. It's missing steps pretty bad no matter what setting I try. I know it's because of the chinese electronics and 127 oz/in steppers so I'm not concerned about that right now.

I don't necessarily want the new build to be a speed demon, I'd be happy with 50IPM cutting as long as I don't start missing steps.

Now to the question, If I were to build the 2006, what would be the optimal electronics package. I'm leaning towards the G540, 361 oz/in, 48 volt PS package from Keling. Would it be beneficial to me to add another motor/screw combination to the long axis?

I'm stopping my production on my current machine because it's unreliable cutting all the MDF. I plan on ordering an electronics package and using it on my current machine and when I'm done cutting out all the parts I need, move everything over to the Joes machine.

Any ideas?

There are plenty of successful builds of the joe2006. He used 200oz-in motors. You don't need dual X-axis for it.

I guess I'm gun shy about being underpowered like the one I have now.

I'm not saying that you must use the 200oz-in.
Your eye on the 361oz-in Keling is alright too.

I think much will depend on how well you design the linear motion of your CNC and its weight of the moving parts. What is now well established is that a joe2006 has been very successful for many builders and you can get a feel for what works by studying that model. After which you may adapt that model to your version and requirements.

127 oz/in with a crappy controller and driver seems to be the issue.

Joe was getting something like 80 ipm cutting speeds with his hobbycnc electronics and the 200oz steppers
I think there will be a significant performance increase with just the g540 alone provided you use an adequate power supply. The 48v 7a version seems to be the optimal choice given the g540 is limited to 3.5a.

I've read quiet a few joe2006 build threads, none used dual drive on the x axis, all had great experiences.

I just ordered this setup from Keling.

2: GeckoDriver G540 3 axis kit $495.95

1 pcs G540 4 axis driver with 4pcs DB9 connectors
3 pcs NEMA23 KL23H2100-35-4B (1/4” Dual shaft with a flat) 381 oz-in
1 pcs KL-480-48 48V/10A 115V /230VAC power supply

I should have it within a week. I'm going to install these motors on my current setup with my cheap chinese board just to see what happens. I'll then build the panel with the 540 in it.
