and the most worring of all is it's can't cut corners!!! instead of cutting a perfect what ever degree corner it goes to far into the corner where corner sharpening was applied and jabs a piece out of the material leaving a half moon shape were the corner was suppose to be... I rest my case.

One more thing, the Z axis sometimes moves DOWN instead of up when we hit zero all axis, now come the hell on, what the hell man!?!? I can't baby the damn machine ahole day, if I punch in a command I expect it to follow it now only follow it some times?!?! how can a person work like that?

I figured as much, I did not get any help from my other posts either. No1 seems to be able to help me. Even the builders of the machine are usless. I reacon the clown that was suppose to set the machine up to work proberly with Mach3 is clueless. I asked him for basic things I expect from the machine and get round about awnsers translating into "I'm a dumb ass" and don't know how to do it. I really feel like telling them to take the machine back and just buy something with a working program.

Why the hell does the stupid piece of crap FEED Rate stop working after I paused the machine and restart? How the hell do you get it to speed up again, it's starting to really piss me off now. 2nd, why the hell does the stupid piece of crap after I have to zero all axis so I can restart the job becuase I can't change the feed rate after I paused it does the job start 0.2mm lower than what it's suppose to?? Can't the stupid piece if crap remember what the hell I zero'ed it on!?!?!?!?!?

FYI - If you ever want to buy a CNC Router, DON'T BUY FROM UNI-CAM!!!

Rant off.

General Mach Discussion / Fimec Spindle tool weight limit?

« on: May 11, 2011, 07:19:41 AM »

Hi guys,
I'm really new to the forum and would like some help . Does any one know what the tool weight limit is on a Fimec ES915 air cooled 30k rpm spindle? We need to mill the table down with as big as possible rose or face mill cutter. Obviously the spindle might not be strong enough for a big/heavy one.. Gonna mill Alliminium - 1x1m in size and 0.1mm steps.
thx

We are also in the process of cutting hardened steel rotary die. Smallest cutter is however  0.1mm, also V-Bit carbide and I see it broke this morning, bleh. Will just have to try again a bit slower.. It's being cut on a HAAS Mini-mill with 6000rpm spindle..  Good luck with your job, you going to need it;)

CV Turned on with a 0.01mm distance tolerances seem to be the answer if you looking for faster engraving and sacrificing as little as possible accuracy. I also read that a "smooth stepper" might help?

I've been reading as much as I can since I joined , I did read that one person say that a weak servo motor might also be the cuz for the jaggedness when engraving a arc at high speed, any truth in that? We have a Delta b series .75kw ac servo drives [comes with encoders fitted]  or possibly that "his" machine was to flimsy, our machine is 1.2tons so it's not flimsy i think..

We just got our CNC Router and also getting rounded corners in CV mode. ES cuts perfectly but takes a lot longer. It's the first time we are using Mach3.
