Wood processing CNC router, 4 axes - first test

This is the first test of Strasmax / Wood Masters new wood processing CNC router, that will have, when finished, 4 axes. In this video, just Y and Z axes are working, X double screw axis is not configured yet.
The characteristics of the router are as follows:
- 2100x1100x300 mm (active);
- Ballscrew Ø25 x 10 (x2) on X; Ø25x5 on Y; Ø16x5 on Z.
- Ø25 supported linear guides on X and Y, Ø30 un-supported linear guides on Z, all with linear bearings.
- Structure: aluminium profile 90x90 mm, heavy; Steel tube 80x80x4 support frame, with castors and equalization screws;
- Stepper motors Nema 34, 12Nm;
- Suhner 1050W spindle with ATC;
- Kinko 2M2280 stepper drivers.

did you use metric t slots or standard. I was checking into making a similar setup, but can not seem to find rails that will line up with the t slot locations. Did you run into a similar issue?

@caelebaby

Yes, all the profiles are metric, from Bosch, so the slots are 45 mm apart. The supported rails are 25 mm, there is one type that has the fixing holes at 45 mm too.

hi, i have just bought 3 2m2280 drivers and 12Nm steppers, could you tell me how you wired your drivers to your controller? and what settings you used on your driver? thanks

@ihaveasony

I am using a breakout board I designed, any breakout board will do with some tweaking. I use the exact connection schematic in the 2N2280 driver manual, with a 12V common supply and 1k resistors in series. I am using the STEP/DIR connection (compatible with Mach3) and the FREE connections are supplied by a logic using a combination of Mach3 charge pump signal, and the error signals based on the alarm and limit switches. There are some explanations in the Mach3 manual for this logic.

Sorry, there is not enough space in Youtube replies for the complete explanation, contact me via CNC-Zone personal messages (search 107251-my_new_4_axes_wood_proc­essing_cnc_router.html thread). Good luck!

Thanks for the reply, is there a chance you could send me your email address so i could send you a docuement showing the breakout board am using? drivers and motors are expensive lol, last thing i wanna do is misswire!
