Ready for next project

[Guy Smiley]

Again I'd like to thank all of the members here that have helped guide me through my first project, "Hoping it Works". During the time that lapsed after the completion of the project I have picked up some components to use for the next. Though they came from surplus factory equipment, I tried to pick out the best operating ones. They are as follows:

2- 1"x40" linear shafts with end supports and 2 pillow block each.
2- 16mm x 640mm (approx.5/8"x25")shafts with linear bearings(4pcs)
1- 1/2"x1tpi-8startx42" ACME drive screw with plastic anti-backlash (spring-loaded) nut.
1- 1/2"x8tpi-sgl startx25" ACME drive screw with flanged plastic nut (no anti-backlash system)
1- 1/2"x5tpix5"travel ballscrew with nut, bracket and bearing end supports.
1- NEMA34 Sanyo Step-Syn 5v, 2.5A, 200steps/rev and has 6 wires
2- NEMA23 Powermax2 Model P22NSXA-LNN-NS-02 35v,3.3A and 1.8/step
bipolar series
1- NEMA23 Powermax2 Mdl M22MRXB-LNN-NS-00 65v,2.3A bipoar series

I also acquired some sprockets and belts for reduction. I also plan to use the Xylotex 4 axis box and Mach2 that I use with my current set-up. I plan to use a 1 1/2hp router on a moving gantry system.

With the above equipment, I'd appreciate it if somebody can offer some info/opinion on these:
1. Can I use the above mentioned NEMA34 stepper with the Xylotex? Can I use the 3.3A Powermax2s with the Xylotex?
2. Will a 3:1 belt reduction give me optimal performance (accuracy, torque, speed) with the 1/2"x1TPIx8start drive screw combined with the above 1" rail system?
3. Can anybody help me figure out the suitable gantry wieght, top speed of x-axis(long axis in #2 question) and mm/step resolution? Note: Am using mm units for my G-coding.

Thank you for all the help/info!

Also, since the Mach2 can control 6 axis. Can I install a switch for the motor lines to avoid socketing and unsocketing the motor connectors? I plan to replace the drive screws on the first machine to be the same as the above planned configuration. Thanks

1) The 34 should work fine, as it's only 2.5A. The 3.3A will havbe to be run at 2.5A (Xylotex Max), so you'll lose about 25% of the torque. The Powermax voltage ratings are Max Voltages, btw.

2) I think "optimal performance would be dictated by a lot of things. Which motor, what voltage, how much weight your moving, how fast do you want to go. Anywhere from 2:1 to 5:1 would probably be in the ballpark.

3) I think it's pretty hard to try to build to a target weight. with a XYlotex, I'd try to make it as light as possible, and as strong as possible. Unfortunately, it's tough to have both. The lighter it is, the faster it should go, but you don't want any flexing.

Resolution depends on what you want to do.

Do you want to wire two sets of motors to one drive, and switch between motors (machines)? I would think that would work, but I wouldn't try it personally. If you're new machine will be better, why would you use the first one, especuially when you can only use 1 at a time?
