my cnc troubles continue and a note for my customers!
Firstly, thanks a TON to those who have pending orders with me, your patience is greatly appreciated! Roadrunner000, Cnlmoore, Seawolf, JoeMagiera, P1001, and anyone else i am forgetting!
I purchased a 2500.00 High frequency spindle for my cnc, which should have made my productivity go through the roof. It should have taken my cut time from 30 - 40 minutes a sheet, down to 7 minutes. But, unfortunately, all it's given me is a complete F*@&ing headache and a machine i can't even use.
I have emailed and called the manufacturer www.shopbottools.com almost daily for the last 3 weeks, trying everything under the sun to figure out what's wrong with the damn thing. Here's what it did initially after installation. It would plunge in the bit, and start to cut, but move really slow, and make a nasty chatter sound, and it wasn't cutting the correct shape/distance, and cut jibberish. It was supposed to cut a square, i get a bow tie shape.
With some really good troubleshooting help from Dave at ram controls, (4 solid hours on the phone) it looks like the problem has been narrowed down. The spindle has a max RPM of 18000 at 2.2 HP constant. it is NOT making the correct rpm, it's substantially less than 18K when set to max. Dave helped me eliminate electrical noise/interference by testing all the variables, running a preset cut file each time. If we removed the cutting bit, and ran the file, i could visually see the machine was making the correct movements. only under load, cutting, did it screw up.
Our test that really proved it, is i went in and made a bit profile, and slowed the machine movement speed down to 1" a second, and set the spindle RPM to max, and it cut just fine.
I should be able to cut 3/4" inch deep in a single pass, at 5 inches per second. So something in the spindle/spindle controller is wired wrong from the factory, it's defective, or they sent me the wrong one for my make/model of machine. I'll be in contact with them tomorrow on the phone to see what's next. I already emailed them all my testing info to PROVE thier spindle is the problem, which they have never even considered.
Dave and I went over my breaker box, wiring, and junction box, verified it was at 220 with my meter, and any other things it could be. only thing i wired in was the main power to it, and the cable that runs from control box to spindle, and it only goes on one way.
Sorry if this long and boring, but i know the guys who have ordered from me need to know what the hold up is! Again, thanks for your patience, and huge thanks to dave for figuring this out when the people who made it couldn't!! I'll update this thread as soon as i know what the hell is going on, and when i might be up and running again. Also, thanks to everyone who has Pm'ed me for cabs/parts, i just can't take any more orders until i fulfill the current orders! Brett
