Its Sunday here and Ive been out of auction for almost a week
, i am feeling a little better and have taken the opportunity to
1. Draw up some of the laser cutting parts and send them off so that they will be ready for folding this week.
2. Milled the other half of the hinges for the rack doors. (will post a pic later)
3. Ordered and received a Smooth stepper from Peter Homann (took 3 days from send me...to delivery - you the man Peter!)
4. Chased up cnc4pc with the controller stuff, he must have some major inventory issues (hasn't even shipped yet, it happens).
5. Made up the Z motor mount (will post pics later)
Experts wanted:
1. I have 2x 269oz 2x 387oz 2x 425oz step motors from PH
http://homanndesigns.com/store/index.php?main_page=index&cPath=25 my plan was to use a 269 for my X axiz and the 387 for the Z axis is this the best option?
2. I brought some Gecko G251 for the drivers assuming they would work fine - will they?
3. Is it possible to have a third axis that when enabled (with a switch) homes itself, then goes to the current z axis position, then mirrors the z axis?
Other points I've been thinking about:
1. My pendant controller is going to have two MPGs one each for Z & X i assume i can do this with mach.
2. The door should really be on gas struts which are expensive, what are your thoughts on having a air ram open the door? I have plenty of air rams and fittings so it wouldn't cost hardly anything.
3. I would like to use the old mounts from the old z axis leadscrew if I do so ill have hardly any clearance (the center of the leadscrew is only 25mm away from the bed) if i do use this mounting position ill have to use belts as the motor center is 30mm to center. The X is belt driven anyway so its not a huge deal, if I do use a belt then i can gear the axis should I change motors and take advantage of the gearing?
