As the flexspline flexes does it not acquire an angular deflection which would not work too well with rollers, but balls would accommodate.

Me too :cheers:

If not too cheeky I would like a copy :cheers:

Stepper has a controller mounted on it's end with a 10K pot. to control speed. Air is just a 24v sol. valve.

24v is supplied to stepper and valve from my main control panel for ON and via an...

Peristaltic pump driven by a stepper motor, since it doesn't rely on the design of the nozzle for any metering duty ( hence allowing air pulsing) you can use any sort of concentric tube system, the...

I have found that these type of misters to be fiddly to set consistently, so decided to knock something up that behaved how I thought it should.

Been following this thread mostly for the amusement it provides :D

Are you hoping/assuming that each of the paired gears will mate with its corresponding pair with the same degree of engagement,...

That's the point really, I don't want high speeds I want more torque. :D

It is a 400Hz motor so that would still give me 6000rpm, my VFD also goes to 1000Hz should I want a bit more. I do...

I have an HSD 6Kw 380v 2 pole router spindle which I would like to use on my VTX1 mill. I am considering rewinding it to be an ~ 2 Kw 8 pole 240v spindle, so that I would have a lot more torque at...

Vexta 5ph steppers will give useful torque at 3000 rpm and 1000 steps/rev with their 240v drives - some good bargains on eBay

I decided that I might want to occasionally move my mc, so put wheels on it, but also have adjustable feet which I use to lift the wheels of the ground when in use.

Rule of thumb - 1% per 1000psi volumetric-ally ;)

Oil is compressible ie: springy ;)

Still interested, have you made any progress on this :)

There was a Vexta 5phase stepper with combined 36-1 gearbox on eBay for $49.99 this week. 0.01 deg/step

Vexta 5 phase stepper with 50/1 or 100/1 harmonic drive - 1/2 step will give 50,000 or 100,000 steps per rev.

Simple and small with very low backlash

I am guessing you are using either W8 or W7. I will fix the problem in the next couple of days.

Getting same message on WINXP

Yes I would be interested - any pics yet

Precisely the point I was making ;)

Where does the sliding come from :confused:

[QUOTE=UniqueMachining;1240953]Gerry
Hopefully it will be fully compatible with Mach3.

Hopefully it will be Standalone :D

Slight bit of finger trouble :o

Were you a diplomat in a previous life :D

You could use Vexta 5 phase steppers, half step- 1000 spr ,with 5mm pitch would give you 0.005 mm/step. If you use their drivers you can still get usefull torque at 3000 rpm. :)
