Re: New Build: Denford/Sherline MicroLathe
Thanks. Part of the reason I bought this setup and not just the Sherline lathe is because it came in the steel enclosure, which will allow me to operate it in an office space (vs a proper shop). Thankfully the Denford layout is pretty nice, with plenty of room in the back for the electronics (I adde...

Re: New Build: Denford/Sherline MicroLathe
Got it. G98 it is then. I've managed to get this dialed in as close as my dial indicator will get me - about 10 microns. Not bad, but I can do better I think. Need to get a new indicator with better resolution.

Re: New Build: Denford/Sherline MicroLathe
FWIW, I have skimmed through most of the 403 page Lathe user manual and when I look up G99 there is nothing anywhere that says nothing will happen if it's active and the spindle isn't turning. If the spindle is turning, I am now getting movement so thanks for the tip. But is it possible to command t...

Re: New Build: Denford/Sherline MicroLathe
Ahh. CNC on a lathe is new to me! I pulled that code right out of the Tech Bulletin, so maybe that should be updated to explain how to do the same with a lathe. That said, when I try G01 Z5 F250 ...nothing happens. I don't get an error but the Message Windows says "MDI..." while doing noth...

Re: New Build: Denford/Sherline MicroLathe
Ok first question: I'm trying to dial in the mm/rev numbers for the lathe axes in the wizard, following the instructions in Tech Bulletin 36 . I have moved the axes to the middle of the machine and in MDI entered: G91 Z5 F250 When I run this, I get a "502 Invalid G Code" error. I can jog b...

Re: New Build: Denford/Sherline MicroLathe
Awesome - can't wait. Well, I can wait because we had a major server implosion at work this week and I'm dealing with that, so good timing!

New Build: Denford/Sherline MicroLathe
I've posted a few threads here and there over the past couple months, but here's the official build thread. I'm just about done with it at this point and I'm down to dialing stuff in. IMG_7775.jpg First, the photo album: https://flic.kr/s/aHBqjBiFta I bought a used Denford CNC Lathe a couple months ...

Re: Wizard PLC function to change spindle direction and enable?
Outputs on the CNC are not switched by an relay, they are switched with the software and can switch an relay. You like to make simple things complicate...😉 It's not about making things complicated - I didn't think I had enough wire to the motor (which has a custom cable I had cut short to reach the...

Re: Wizard PLC function to change spindle direction and enable?
I just pulled 24V from the acorn into the relay NO terminal and I'm feeding that to the motor. It's all up and running now. Had to rejigger a bunch of my wiring to get it to reach the relay board but it's working: https://www.youtube.com/watch?v=dhT1MtVoKG4 Yes, I'm aware of how bad that pulley is. ...

Re: Wizard PLC function to change spindle direction and enable?
I agree with not wanting to deal with the PLC stuff right now, especially since I'm still coming up to speed on Acorn as a whole. However, the wiring was cut to fit the distance to the Acorn board, not the relay board, so this poses some challenges. I may be able to flip the relay board so the relay...
