What did you use to connect the motor to the super dust deputy? That black pipe?

Lowes and Home Depot sell various size sheets of 1/4 MDF

Hopefully the linear bearings (that have a lot of plastic internally) that are attached right behind the plate took no damage from the heat...

If the problem started after tying the shields together how about undoing them and seeing what happens? Seems fairly logical to me.

Also. Shields on steppers are supposed to be connected on ONE...

Eh. If you're looking for speed you definitely don't want 1600 oz in motors on such a small machine.

I really think before you buy anything else you need to do more research. Like Gerry said, you...

Eh. They come with right angle connector cords.

Yeah. Except for their astounding QC issues and customer service problems. Anyone considering should take the time to read up on FLA

It's a Bosch Rexroth bearing. You sure it's not a
R1671-214-10?

My advice would be to contact Bosch Directly.

Can you attach a picture of the actual bearing? Specifically the number on the races?

Already exists. Cncrouterparts.com Users is the group name.

Hard plunging will kill router bearings relatively quickly. It'll do the same to spindles. Ramping in is the way!

I have a set of the nema 34 Motors and some nice 20ft igus cables with xlr connectors on both ends. I'll also throw in the 5 panel connectors needed with wiring. All you'd need from cncrp is the...

Steppers will eventually burn you. They loose steps. They heat up nicely on long jobs. Inefficient. Noisy. And the list goes on.

I lost a 5 hour 3d carve yesterday because of them. So hi ho.. ho...

Link to the servos.

I'll be keeping the 3.2:1 reduction.

So. If someone were to hypothetically be replacing their nema 34 960oz in steppers from cncrp with servos, what should the kw rating be?

Eh.... both the rack and pinion are steel. The pulley that drives the pinion is made of aluminum.

Could you imagine how fast a steel rack would destroy an aluminum pinion? Lol. You wouldn't make...

This was addressed by Cncrouterparts not long ago. I think the consensus was it's not possible since everthing is different. Including the extrusions. Apparently it's cheaper to buy a whole new...

The ideal solution would be to space the rack out with some flat stock like cncrouterparts does vs the spacing the pinion gear out more. It's basic engineering 101. The flat bar would have much more...

Think I'm taking this advice. Gerry, are you currently using these?

I spoke to the people at DMM they seem pretty willing to work with people and customer support seems on point so far.

Eh. It's moreso about the shipping fee. Canadian customs is a different story. They generally do not collect customs on stuff that isn't alcohol/tobacco

I declare EVERYTHING every time I go...

Just as a heads up guys I've been trying for over two weeks now to get a set of servos from these guys to test out. I live slightly over an hour from their sales office/factory and have gotten zero...

Yeah. It's definitely interference from the vfd. Once I got some shielded cable and properly grounded it my issues left.

After coming to this forum, and reading the things posted here about FLA, I'm not entirely sure why someone would send their money to them in good faith.

Not really sure why anyone would do...

Uh. Yes. Plain and simple. I have been running my rack and pinion machine for close to two years now on the same set of pinions. Mine haven't even begun to wear yet.

If you have poor meshing...

Should we start a pool to see how long it's going to take Nate to refund Keith's money and another one to see how long it'll take to get these bad drives recalled and replaced? Oh. And those rack...

Getting rid of the atrociously poorly toleranced fineline automation pinion drives in favor of the real deal cncrouterparts ones fixed the issue! Like the saying goes "Don't be fooled by cheap...

Also here are some pictures. So people can get an idea of just how bad the fitment is. As well as the poor rack engagement.

Just to shine some clarity on this, the drives that sybilsurf has aren't the ones from you guys Ahren. They're the "copies" we've been discussing. The "other guy" is just using a pinch collar of some...

That is the one they use for the structure. But I've never been able to find the table extrusion on there. I believe it's a custom profile from somewhere

Yeah. Htd belts are not good on gt gears. You can do it but that's such a sloppy mesh between the two. Which WILL create backlash. Htd belts will also have the teeth shear right off if you hit...
