For those who find this in the future via search.....It was the power supply. I

So may setup is this Old PC running XP, Mach3 to the Parallel Port to the G540. From the it's CNCRouterParts, Nema 23's and cables. I'm using a 48V 10A power supply to power the mess.

The setup...

The bit doesnt appear to be climbing out out of the collet. In fact I have hard time getting it out of there at all, so much so that I purchased another collet for the planing bit.

I havent planed...

So i did find that my router cable was running very closely parallel with the z axis cable. So separated that out, ran a test, same drift.

Checked the clamping and it's in there solid.

I ran...

i'm looking selling a series of items based on images of various motorcycles styles. The images used are my own, and even then converted to very basic traced outlines in autocad for use in routing on...

That did it! It seems like every time I correct one setting something else comes undone. While resting at zero, after I set the ramp velocity to limit to 250ipm, It threw in some 90" offset from my...

I finally got the Z-Axis finished an mounted. Pics to follow soon. Everything seemed to be jogging fine until I noticed Mach3 recording the steps wrong. I set those via the Axis Calibration section...

This clip is running the Roadrunner sample after ensuring the commands do not exceed what the manual jog revealed to be the machine limits:

Progress! (excuse the mess)

Been spending late nights fabricating mounting plates and covers. Finally got everything mounted and aligned (as good as this pass will allow), and now am learning some...

Little further along today, time has been a very scarce commodity lately. I've got the bed finally mounted, so now I'm to the point of installing the leadscrews. So now it's got me wondering, what...

Given that the link is 6 years old, I'm not surprised. Luckily the wayback machine had the list archived:

After reading rbraekings comments, I searched around a bit more an found some reasonably priced enclosed Nice 603 BB Thrusts on Amazon. Funny thing is I ordered 8, got the first 5 two days later in...

I have the acme screws already purchased, they're still in the packing tube till I get bearings for them to rest on, should be in next week. I also have the same lengths in single start before I knew...

Had to stop work on the CNC to build a nursery...and sure enough...no free time to work on it since!

I haven't made much progress on the build since my last post, but I did manage to snag a G540...

It's coming along slow, but getting there! The cost is starting to get to me as i look at the higher dollar items. the electronics were a given, the dual x axis redesign added another 6ft length of...

Found the individual ball, no idea how to get it back in, so i'll probaby just replace it.. until then it remains for testing purposes.

I have the bearing lined up on a small piece of MDF such...

I tried adjusting the set screw on the top but it just seems to get worse. some of the bearings i have move smoothly, while others seem to almost rapidly catch and release.

In one case where i...

Nearly have the Y Axis complete. There's still a small bit of binding, but nothing too bad, I'll fab more accurate parts later. The bearings seem to have inconsistent preloads...not sure how to set...

Should have a gantry assembled by the weekend. I'll be making another trip to the store to get a decent respirator before making any more MDF cuts though.

In the mean time. Here's the revised...

Small update, some cuts made last weekend. This weekend, a plate for the z axis to mount to. I wasn't planning on using aluminum in the build, but a few small plate became available.

Good thing i haven't cut too much!

Now I've talked myself into a 4 axis system. I was thinking about just continuing on with the system as designed and just moving the two x-screws closer to the...

I could probably torsion box the sides at a width of an inch or so. Think that would be enough?

Starting cutting gantry parts today. I forgot how much I hate my portable table saw. I can eyeball...

Not sure if this is out of the ordinary, but I originally(before deciding to go 20mm) bought a set of SBR12 blocks, they all had 4 bearing races.

I'm about one weekend away from starting to cut the gantry parts. Before I do though, is 4 inches high enough clearance from the bed, or maybe even too much? Im sure it all depends on the purpose of...

I have yet to use 8020 yet, but I would drill holes in the mdf and use the 8020 tnuts to pull the extrusion tight against the mdf. threading the tnuts first, then sliding the extrusion down the...

Spent the afternoon moving some stuff around a double checked my table downstairs. Good thing too, it's a couple inches shorter than i thought. So with that in mind, i've shortened the Y and the the...

I do occasional dovetail work with a jig, but after reading through the dovetail threads, I'm considering leaving the x axis bed length short where the stepper motor is so the full length of the...

Y'know I saw that, and i had it in my notes, but totally forgot to design it in. Thanks for the reminder!:cheers:

The base the X rails are attached to is 48"x 39"x 3/4". This will then be resting on one side of a spare dining room table in my basement (dimensions approximatly 48"x72" with 3.5" posts and 3"...
