Yep, should have been more specific in my last reply.

Yep, 100% a win7 x64 issue. Works like a champ under windows 7 x86

Alright, it seems as though Mach3 doesn't like Win7 x64 :/ Installing the 32bit version now. Well, so far this has been an easy problem for you guys to troubleshoot....

Ok, I just set my x-axis direction to pin 2 and tested pin 2 on the back of the computer with a multimeter. The voltage is not changing when I hit jog left and right so it's possible Mach3 isn't...

Hey Guys,

I've been working on converting a milling machine for years and I'm finally getting around to the electronics side. I have a test setup in my living room right now just trying to see if...

Hey Guys,

I'm trying to learn how to generate Gcode and run machining sumulations in Catia. I'm just playing with a couple rough models at the moment but I'm having a bit of a hard time. For...

Yes, I can say for certain that no balls were lost when I took them apart. I filed a claim through paypal and Chai was very quick to mail out some replacements. It appears as though all is well.

Yep, ran em all through the caliper. All of them between .1235" and .124". 2 of my ballnuts had 50 balls and I was very careful not to lose any when I took them apart. It appears as though Chai at...

ok, well it's all back together with 17-16-17 and I figured the noise was due to no grease. What would be an appropriate grease to use?

Alright, I'm an idiot. I took my ball nut off of my ball screw and I should not have done that. Now that it's done, I have no choice but to put it back together. It's a linearmotion2008 1605...

Yep, that's pretty much exactly what I came up with except I'm going to use larger bearings and run the ballnut on the inside of the bearing sleeve with the pulley on the bottom. I was thinking about...

Hey Ben,

I'm using 16mm ballscrews and the area I have to work with on the ballnut is 28mmOD x 32mm (1.25"). I'm getting a quote on some 30x47x9 mm AC bearings from NSK. I'm keen to see what...

Exactly. I can find 30mm, 25mm but no 28mm, which is ridiculous because I can get 28mm tapered roller bearings but, of course, they are WAY too thick.

A 1mm thick sleeve may be my only option but...

I'm designing one now for my PDM-30 using 2 angular contact ball bearings on a ballnut with a piece of aluminum sandwiched between them. I'll be using a waved spring washer and a snapring to hold it...

I have the massive Kelling 1125oz/in servo motors and I'm building a rotating ballnut to drive the Z axis on my PDM-31 (RF-30 for the US folks here). I'm looking at 5M x 15mm GT2 belts and pulleys...

OK, I'm an idiot. I didn't realize that B&B Manufacturing do have all of their prices and everything listed on their site, their prices aren't bad AND they have GT2 5M & 8M pulleys and sprockets. ...

I just bought a bunch of chinese ballscrews/nuts from Linearmotion and I am going to need to turn one of the ballnuts down to mount bearings on it. The body of the ballnut is apparently 28mm (I...

Ok, check these guys out. https://www.beltingonline.com/

This is what I consider reasonable prices on this stuff. The shipping is INSANELY expensive though. I sent them an email to see if they...

Well THK came back with a price of about $800 for that ball nut. I couldn't hang up the phone fast enough. I am going to modify a chinese ballnut and mount the pulley to it so the plan has changes...

I asked if they had bigger L timing pulleys and they want to make something custom for me.... lets see how expensive this is gonna be!

https://tech.thk.com/en/products/thkdlinks.php?id=359

The...

Not entirely sure but I was thinking I would try for a 2:1 ratio and the one needs to be big enough to machine so I can mount it to a THK DIR 1605 rotary ballnut. Probably something in the...

These guys seem pretty reasonable but their pulleys are really small.

Yeah, their prices are asinine. $60 for a 30 tooth L type pulley with a 1/2" bore.

Thanks for the replies guys. I have mostly just been looking on ebay and it's a bear market. I just got a quote back from Martin through Wajax at almost $200 for a pair with no belt.

I think...

I'm getting pretty irritated trying to find timing pulleys/belts. Ballscrews are fairly easy to find but trying to find belts and pulleys for a reasonable price is a pain in the ass.

I'm trying...

I have this exact same set of equipment and I also got it from Kelling. I'm just building my box but my current concern is that the motors are twice as powerful as the power supply so I'm wondering...

Well, you're certainly putting my case to shame and made me think that I probably need to add a whole bunch more junk to it lol. No idea how to wire up all of the over ride controls you have there...

Well, it looks like almost as soon as I posted this thread a whole bunch of new forums popped up over night! You're Welcome... lol :p


Yeah, they actually have 3 conductors (the 3rd is just a...

Alright, there are soo many bloody forums on this site I have absolutely no idea where to post this so it's goin' in here.

I'm building a CNC controller box for my little milling machine out of a...

I placed an order with Keling a few weeks ago. Their service was good, the packages were very well packed and shipped quickly. They also went out of their way to help me.

I won't hesitate to...

Anyone?
