That's not the fault of Path Pilot, it's the fault of a crappy CAM post processor ; Path Pilot does not require a feedrate value in every line.

Don't forget to :

- properly ground the VFD
- properly ground the PSU powering the drives

Omio doesn't run any wires but relies on the crappy screws holding the components in the case.

My X4-800 came with a VFD which could also handle the 1.5kW spindle , I doubt anything needs to be changed, just plug n play. From all the pictures and movies, I've seen the control box for X4 and X6...

Such UPS units won't like things like VFD's connected to it. I'd seek some expert advice before plugging in a CNC machine, you might otherwise kill the UPS. Also a UPS doesn't always give a nice sine...

You want more bearings, not less. And I personally on my X4 find the 800W more than enough. It's not rigid enough for steel and in aluminium with a 6mm cutter you'll never need the 800W. Mine is an...

Download a trial of CAMBAM, which is about the cheapest package I know of at around $120 and allows 40 sessions of full use before dropping to a 500 line limit, and do a side by side comparison of a...

I'm also considering replacing the electronics on my X4-800 but am looking at a different route (as I'm using LinuxCNC now) ; has anybody here tried a Leadshine MX3660?

My 3040 doesn't have a bolt-on motor mount : it's one big casting that holds the Z-axis bushings, Z-axis nut and the motor. So no way to align that in any direction. See the pictures at...

If the rest of the machine was 100% square, straight and stiff that might be true... my 3040 was so badly out of alignment from the factory I did not trust any of the parts supplied as a reference....

If you are going to replace the bed with a slab of aluminium, try to get tooling plate quality, which is cast and thus has no stress in any direction. This means that drilling won't warp it too bad,...

I would not buy the X6-1500GT for a business. The X8-2200L is better suited with it's more stable guide rails. No idea if it will do the amount of hours you want, mine has done about 15-20 hours...

New belts are readily available. I got a set of them from http://www.bearingshopuk.co.uk/mxl-480/
Either the 12 or the 13mm will do
Pulley's indeed have a 1/4" bore

The three left should be chassis ground indeed, but just run all the wires and don't connect it to the chassis to prevent ground loops and other nasty stuff (not all the boxes are wired 100% correct,...

The six pin unpopulated header XYZ is for the home switches ; ground for all three is the same (the left row from what I can see on the picture)

Here is my solution to the problem :
331810
This works especially well for larger series : I mill out a pocket slightly larger than the PCB. Then I know it's flat and perpendicular and I can even...

Haha "technical secret" ; it's nothing more than a normal cable, all pins connected straight. Just buy a serial extension cable with all 25 pins connected , and if the board side doesn't match (many...

A quick estimate I got for such a bed for a 3040 size machine, made from C45 carbon steel, would run well over USD 1200, if I wanted the same 0.01mm/200mm accuracy....

I've noticed the same with my X4-800 (the model with the round unsupported ways) and after several jobs which didn't turn out quite as I hoped I bit the bullet :
...

Have you tried different software then? Mach3 (which usually is shipped with the 6040 machines) or perhaps LinuxCNC?

I've sent them a mail a while back to which I got no response. Another mail to Omnio is underway, but I'm not expecting very much from them....

EDIT : just got a reply from Lance saying they can't...

Can any of you X6-2200 (or X6-1500 with USB) owners help me out?
I bought an X4-800 some time ago and now want to drive my VFD from LinuxCNC. I already have an analog 0-10V signal but the hookup on...

If you want to mill aluminium I would choose the X6-2200L for sure. With it's lineair guides it's stable enough, motor with VFD has more than enough power. With the smaller X4-800 I've done engraving...

Something to definitely also do if you've got the case open : earth your VFD !
The E terminal on the lowest level is for earthing your VFD. A with all Chinese electronics, their grounding is a...

Spindle control in the stepconf wizard
Hard to say exactly but perhaps you've set PWM or some other feature while you are not using it or something like this?
What hardware do you have? My X4-800...

That sounds like an incorrect machine configuration or picking up interference somewhere....

You will want to upgrade LinuxCNC to the latest 2.6 release, loads of good updates have been done... check the wiki article at LinuxCNC Documentation Wiki: UpdatingTo2.6 for upgrading.

I'm considering a cast aluminium T-nut plate for my 3040 , Gussaluminium T-Nutenplatten
Not cheap but it's very flat, makes the frame a lot stiffer and doesn't resonate as bad as the current bed.

I too don't see any advantage to the 2.2kW spindle.
I recently purchased an X4-800 from carving-cnc.com which comes with an ER11 collet spindle.
The smaller collet and thus small spindle diameter...

I've just bought an X4-800 with LPT board.
I now want to interface the controller to the VFD. Can anybody with an X6-1500 USB perhaps open up the little door on the VFD and make a picture of the 3...

Harsh noise indicates vibrations. How did you mount the box to the milling machine?
Also the aluminium of the box might be a totally different sort than the other plate you cut previously.
On my...
