could be the Humphrey valve screwed into the right side of the solenoid valve you have labeled C. the diaphragm inside is mostly likely junk. might check it out.

First off,
thank you all for the replies.

The material is mild steel, piece of square tubing to be exact. just something I had around I could test on.
I change the hatch to 1mm to better...

Have not had this laser long. 30w split unit from ebay.

I'm having a hell of a time getting clean marks once hatched.
if I just follow the contour, they look great.

Yes, it was in P0.00 = 0

its 220v single phase, from a 30 amp breaker in a sub panel.

if I do need a line filter or reactor, do you have any recommendations?

thanks!!!

Had a chance to check and change parameters to what is listed above.
Then I ran the auto-tune, still errored out with OV3, but might have ran longer before doing so. I didn't time either run, so...

I have the parameters set to match what is on the spindle.


P2.01=4.2
P2.02=400
P2.03=24000
P2.04=220
P2.05=11.2

Do you think it would be better to get the 5.5Kw version? I think that is the closest rated one to my spindle.

I have all the required parameter set, at least that I know of...

thanks for...

Getting a new spindle dialed in here.

When I run the autotuning function; 5 minutes in, the VFD errors out with a OV3.

The manual says that is for: " the input voltage changes abnormally", OR...

Thanks for the response George.
Yes, running mach 3.

I adjusted the Max Step frequency in the ESS control panel in mach 3. It was set @ 256, took it down to 128 and ran the program with the...

Guys,

Having a strange issues that started last night.

I have isolated it down to the z intermittently step up when it was commanded to step down; only while the spindle is running.

So my...

Looking at upgrading to a ATC spindle on the newer style Pro machine.

What is the max weight for the spindle before there are side effects / issues with the z itself?

Or possible weight...

I just smoked my second driver last night. This is AFTER installing the recommended shunt regulator... I caulked the first one up as my fault as I didn't know about the shunt regulator so purchased...

you guys were right. bad connections @ one of the pins. I swapped to X & Y out at the gantry as opposed to @ the controller, and now the issue followed the cable. so then it was a matter of just...

When I get home tonight I will check all the connectors. these don't use the DB9 connectors, they are NEMA34 motors and I used some four pin connectors I had.

thank you, and I will report back...

just got a 4X4 pro up and running. Maybe have 2 hours of cut time on it. Was running a program this afternoon and the z axis plunged and dug a trench is a .75" piece of MDF. I estopped it and...

you may be onto something. the left side wash is .5mm thicker than the right. this would certainly help. I will have to find a thinner washer.


As for the prox switches; i didn't like having...

Hi all,

I have been slowly getting a 4x4 pro machine up and running. Ran into an issue.

the left side of the x axis pinion gear is making contact with the aluminum and does not appear to be...

been working on a cnc router for a while. i came up with this idea for my x axis.
they would work as the support, ball screw and mounting for the linear bearings.
