I need to know how far the motor shaft on the 640 oz stepper he sells protrudes past the bottom of the Z axis mounting plate.... I'm also needing to know how much of a gap should be between the end of the motor shaft and the Z screw (inside the helical coupling).. This information is necessary for me to know how long to cut the 4" flat bar...
If I had the motor, it would be a no brainer... but I thought it would be nice to work on that stuff while waiting to get the moola together, so that it's out of the way and the work doesn't all stack up at once...
It's not a huge deal...
The other thing I'd like to know, is the difference between the MeanWell switching power supply he said he could supply me (not listed yet on their website,but I'm pretty sure he's talking about the
SE-100-48) and the Torroidial Power Supplies from Keling... Is one better than the other? More reliable? Is the main difference just the enclosure and fan on the meanwell?
The meanwell is considerably more expensive, but may be worth it... I need some 'sales' help here...
There is zero info on his website regarding the motors other than the voltage, current, and in oz rating.. torque curves, drawings/dimensions and all that are non-existent...
I like the idea of his stuff being plug and play, but I'd really like some more info on it all... It's pretty vague... and the money for this stuff adds up.... I don't mind paying the slight markup for all this stuff that he charges, as I think it's all quite reasonable, but a little hand holding is expected in return...
Also, one thing I haven't asked him yet, but I need to know, is the BOB... what do I need? What is recommended with his system?...
I will be using the
super-PID controller for the router listed elsewhere here.. I will be needing zeroing/homing switches, E stops, tach input, etc... there may be other inputs I am not yet aware of that I need.. AFAIK, the BOB is the interface for all of this stuff, and I need to select one that has all the ins/outs required...
Finally, the difference between the Gecko 201x and 203V? I think it is just 'protection'.. Is the extra 35 bucks worth it? are the bulletproof claims exaggerations? Are there other differences than the protection? Is this something I should not worry about and just buy the cheaper 201x drivers?
