Not actually that expensive by performance end mill standards, but designed for a machine with a 100+HP spindle. Look at power and torque curves...
Either shim the mount or try and rotate the entire gantry. Though then you get into "is my Z axis off or is my spindle off?" territory, because...
You need to straighten the screw (prior to installation) because a bend isn't going to tension itself out, it's still going to want to whip...
Yup. Wasn't kidding when I said about throwing serial prints in all over the place and testing plugged into the computer. The problem with...
It's based on the electronegativity of the dissimilar metals in an ion-permeable solvent medium, doesn't require an external charge- think lemon...
Have you looked at quadrature encoding to understand what the Arduino is looking for and how it's able to count forward and backward using just...
Also make sure you're multimeter-testing the stepper wiring. One of the phases might be backwards, the documentation may be incorrect, etc.
Never heard of the A3967, probably wouldn't even think about using one. For a production type environment where reliability counts, I'd either get...
It could be done with two separate encoders, you'd just have to attach a couple more interrupts (assuming you're counting with interrupts, I...
Eh, if belts work then they work. Definitely a lot faster for a production environment, in terms of keeping up with the operator. I'm not sure...
This is a true fact. Ditto for Knifemaking Tuesdays, actually. Great insights into developing a product from scratch with minimal cash input. 1)...
I wonder what the repeatability is with belts vs screws. The problem is tracking the rotary input doesn't give you an inherently meaningful output...
I need to update that thread. I say that every time it gets brought up though. It's a lot of work! Ball screw I agree with, a cheap 1204 would be...
Some progress on the Z axis this week. I've had other projects in the shop, so it's been a little bit slow lately. [ATTACH] Gotta figure out...
I see- he's doing flange mount brass blocks set up in an anti-lash configuration where they can be tightened against each other: [ATTACH] The OB...
The nutblocks should have the anti-lash mechanism built in. No other reason to have two per axis unless you're gonna get really nerdy about...
If you're just doing stone and steel, a welded, epoxied, heavy-duty machine is the way to go. The problem would still be the spindle- steel...
Yeah, what he said. Probably one of those things where you just start it, and then pick up the extra components that you missed. Might not be a...
Depends what you're doing. Unistrut is significantly stronger and also has some linear motion options, just obviously not as precise as V-Slot....
Nah, I'm with you; Tapcons or RedHeads through L-brackets is the quickest and most effective way of fastening it down, particularly...
