Yes, its a good alternative for your described use case. Go give it a download. It's free if you're a startup/educator

Sorry, but the previous poster isn't wrong. If you total up your time and cost I don't doubt you would be near the price of a Tormach, in which case, why would someone bother with your machine?...

Dont apologise for asking, we've all been in your position, I want your mill to run too. haha.

The wiring looks okay to me. Use Stepconf to assign your pins and you should be off to a running...

Yep, I had a 66lb strut made for me by a local manufacturer, it works great. I'd suggest it as well.

I was fairly sure that Hoss has a little blurb about just switching the polarity on his motors to prevent this from happening.

Wow, what excellent information! Thanks for posting that!



I'd be very interested in a kit. I have the usual pump that most people buy off eBay, but require the fittings/lines/manifold etc.

Any chance you'd turn me a set of those poly-vee pulleys?

Yes, you should face/bore your jaws to your machine. But moreover, make sure that your spindle is turning parallel to your bed ways. Using a dial indicator is your best bet, held in or on your...

PDB Cylinder has arrived!
3x100mm bore pancakes
12mm stroke
Weight is 6.3kg/13.9lbs

More to follow soon!

Oop, yep, odd, must have been signed on on my phone on my old account.

I'll be able to get you guys some weight/size/other information once I return to the shop on Jan 2nd.

Delivery time would be around three weeks, seeing as that's how long it took for my cylinder to arrive from the time I placed my PO plus a week for me to assemble/test/pack/ship them.

The main problem is that your application of force for the Z axis changes direction when you add a ballnut/ballscrew arrangement. I would imagine the easiest thing to do would be to run dual-shaft...

Clean your pulleys with alcohol to remove any gums or varnish. Make perfectly sure your belts are aligned and not overtensioned.

You would install a zerk fitting (M6 thread usually) into your ballnut and run a flexable line all the way up and then 180 degrees back down the column to your nut, it will move with the axis up and...

I would love more info on your drawbar/pulley setup and linear rail conversion, I have the motor and VFD already, just need to get the parts made and installed.

I would advise you to do your own research on these topics, there's a ton of information already out there that can help you that is available with a simple search.

As long as you're geared correctly and have the right spindle bearings I wouldnt expect any issues! Make sure your motor is inverter duty however, they're designed to handle the extra heat generated...

I'd prefer to buy off the shelf pulleys and bore them to suit my spindle and motor. Worst case scenario I'll just turn my own.

Hey all,

I'm trying to design up my belt drive for the new 1.5HP Marathon motor I have on my G0704, but am having a hard time finding any small bore sheaves for poly-V belts. I'd like to avoid...

Its not just your time machining, its the time that you could be NOT machining that's valuable. If taking the opportunity cost of sharpening your own endmills is worth it, then thats your best bet.

Consumables are what they are: Consumable. Just part of making parts that you have to deal with. I would advise you to do the math: How much is your time dealing with endmills worth against the cost...

Its the sort of thing you have to come to expect with milling hardened materials. This is where inserted tools come in very handy, if applicable. Else, find your local grinding house and see what...

What did that big guy end up costing you landed?

I wish there was an easy way to determine what size balls I need to repack my Y axis. Seeing .0038 of backlash. Any ideas? In theory would it be just take the current balls and increase in diameter...

Its the instant gratification crowd these days eh? Keep on killing it @BTP.

I consider homing switches a necessity, especially if you're part way through a part and god-forbid you lose position or otherwise jam something up and have to re-locate your part in order to resume...

Check your steps per rev setup in Mach. Glad you got it sorted!

If it works, it works. I chose my route because it fits my machining design intent the best, if the D80C is right for you then absolutely go that route!

If you model up a plate I can make it and...

There's a certain point where you start applying lipstick to a pig here IMO.

This is why I have built in a 70lb counterweight gas spring into my Z axis. Also, it will fit quite well on the mill, as others have done so in the past.
