Does the period of the waves roughly match one turn of a lead screw? I'd guess one of your screws is slightly bent causing it to be harder to turn for part of the rotation, and the servo can't quite...

If you have this many questions, you've got a few hundred hours of research you're going to need to do before spending any money, especially if you're looking to pay off debt.
Honestly I'd...
Another thing to keep in mind is how much work will it be to replace a belt. You could deal with it with creatively routed belts and located idlers, but if you're planning on just having a belt go...
I don't see any of the pictures you referenced in the first post.
So you're thinking 4 rotaries and 8 spindles so you can have 2 tools loaded?
A couple issues I can think of right off (without...
How come the Z axis rails are so far away from the carriage? Those little threaded rods are going to flex a LOT at that length. You will need to add a lot of triangulated bracing if you want to get...
I definitely wouldn't assume that doc applies to most generic 24k spindles. First, it shows running at 220v at 15k through 24k RPM. Most generic 24k spindles don't show getting the voltage to...
Do you have any electronics lab equipment (oscilloscope or something similar?)
It could be something to do with supply power as well (power to the VFD).)
I assume you are controlling your spindle...
Depending upon your usage, the advantage of the IGUS chainflex (and there are others,) is it's rated for continuous flex at a relatively small bend radius. If your spindle motor doesn't move, this...
It couldn't hurt, and done properly has a good chance of solving the problem. You will want a cable with 4 conductors twisted (3 phases plus earth,) and a shield. I can't recall off the top of my...
Will it work at all? Sure.
Is it a good idea and will it work at high speed? No.
You'd be reducing rigidity quite a lot by hanging something out on the end of a 10mm rod, even if it's a short...
110V 3 phase is unusual. I'd guess that to run it from 110/120V, you would run it in delta. Wye would then be for 208V (much more common in 3-phase.)
Odd that there are fields on the motor...
Congrats!
I've read very few accounts of customers who regret Clearpath's. They aren't the best bang for the buck power wise (DMM servos are more traditional AC servos, but very inexpensive and...
Just because Windows 10 supports parallel ports doesn't mean it will work with Mach.
A quick search shows that Mach on Windows 10 either doesn't work with the parallel port, or is enough trouble...
What are the voltages and frequencies on that scope reading? Hard to tell from just a pic. Is the motor making noise? (Driving a square wave through a motor would ordinarily make quite a bit of...
Sounds like a tachometer rather than an encoder. Probably not useful for the Machdrive. Most modern servo amplifiers just get the velocity signal by differentiating the position signal, but on...
From the research I've done (not that much,) adding linear scales as a second servo loop isn't really done much. I think most linear scales have slower response than servo encoders, so that will...
Sorry, missed your response way back when.
Head weight will vary a bit between having no collet or drawbar in it vs having a big face mill installed. Also, depending upon the type of spring, the...
Quite a few have done CNC lathe conversions. Generally the lead screws are replaced with ball screws, so most can't be used manually anymore. Biggest issue with ball screw replacement is that the...
The collet holder is probably pressed on. Not likely you'll be able to get it off without damaging the bearings. Those types of spindles are pretty poor in general anyway. Runout is pretty bad and...
Are you sure the fan ran before? Some of these have 'smart' fans that only run when the unit is warm enough to need cooling.
36v shouldn't damage the steppers, but it can certainly damage the drivers. Looks like the PoStep25-32 are only rated for up to 30v.
Might work, might burn something out.
That hall module will only work if pin 13 is pulled up to between 3 and 5.5v and is triggered when the pin is grounded. If it's pulled down and triggered when...
It's not just the insulation rating in a transformer that comes in to play, the volts per turn matters as well. Doubling the volts per turn will likely cause significant unloaded loss in the...
That Z axis plate won't need to be nearly that long. Keep in mind that tool holders have some minimum length (usually at least 60mm flange distance on 30 taper/HSK63 I think,) the spindle nose has...
Having the same speed on the axes applies more to the X and Y. As long as Z is at least half as fast as X and Y it won't impact things much.
Not a bad thing to have the max Z speed equal to X and Y...
I think I would skip the power conditioner as well. As long as everything can handle 32v or so (max you'd probably see on a fully charged 24v battery,) and be able to run at 22v or so.
X2's usually...
It's most likely to prevent the router from getting damaged during transport and to help keep things square while (and after) welding. Ask any mech engineer, rectangles are weak, triangles are...
Right now it looks as if your table will only be connected to the long rails by the 4 corners. They need to be much more tightly coupled. Right now, picture how much flex you would get if the...
I was referring to the photo of the yellow router.
If the lower leg braces being referred to are the horizontal pieces (one with cable drag chain on it,) then those do almost nothing for stability/strength. They just keep the legs parallel. If the...
