Re: Huanyang Inverter how to reverse spindle?

oh...you mean like in the last post before your question?
It's a Y/Delta configuration, so reversing ANY two of the wires will have the effect of flipping the triangle over.
It's the old right-hand rule of electromagnetism:

Re: Control connection issues

Henry: In high-static, and high electrical noise environments, the old shark controllers definitely had problems. I even sold a kit that had users modify the wiring to fix that problem, and it helped many people fix those pesky connection issues. The root cause was that the static-drain/shielding wi...

Re: Shark SD120

Mad Max: Depends on the material and F&S used. Most people only do wood on these machines, and wood parts often only need to be accurate to 1/32" (0.03125"). That's even more true of things like wooden signs, where most people might not even notice 1/8" Inlays, however, often want things a LOT tight...

Re: Constant home position

There is a common misunderstanding of the function of LIMIT switches versus HOME switches. The function of a limit switch is to tell the machine that it is about to CRASH. The normal function of these switches, when tripped, is to trigger an ERROR and immediately stop movement in the machine. That i...

RMC_Florida:

Likely to allow the spindle to come up to speed, in cases where the user purchased the new controller-set spindle speed.

Re: Not to proud to ask for help

I never knew how to update manually because I have to disable the automatic update process to navigate quietly on the internet. LOL....there is no "quiet" navigating on the Internet anymore. Even the so-called private browser sessions are subject to both hacking and data leakage. Run the updates. A...

Re: Invalid Pointer Operation

Crosetti: When you say "open" the file, do you mean double-click on it, or use the standard file-open? Or are you transferring it via a USB flash drive/card? Either way, it sounds like one of two things might be happening: 1) the data for the toolpath did indeed get overwritten / corrupted. 2) the c...

Re: I think bearings are going or gone

MixterX: Definitely clean the leadscrew if there is wood dust on it, lubricate, etc. I attach an old toothbrush to a piece of square wood/tubing using just tape, and that works well to clean off the leadscrew if you jog the mechanism back and forth. Then clean the brush, apply lube to the bristles, ...
