Woodmizer Feed speed on return
« on: December 19, 2017, 09:20:55 PM »
My LT35 had variable speed (electric powered) when taking a cut, but came back at full speed when I held the return lever.

On the LT40, 50, or 70's is it possible to have the mill return at a variable speed on the return as well as on the forward stroke? I've heard that there is an optional wire that can be connected to make it do so, but I'm curious if  you make this mod whether it's an all or nothing mod. Most times I'd like to return at full speed, but I'm building a multi router head that I'd like to have the mill feed down and back over a cant or two, and speed control for this op would be ideal.

   It is possible to make the return a variable speed. When Cutting Edge And I  converted Sliders LT70 to Accuset 2 there was an extra wire in the harness to the H-Bridge just for that purpose. If you chose to not use the feature you left the wire unattached and zip tied to the rest of the harness. When using the feature the return speed is controlled by the feed rate knob,pot, just as when going forward in the cut. Not sure what mill revisions came with this harness factory equipped. You made need to purchase updated harnesses in order to convert to the variable speed return. Contact Sparks at Indy to make sure that is all that may be required.

Hello,
  GMMILLS is correct. Any mill with Dual Access H Bridge will have a wire ( yellow) that looks like it needs plugged in. This will give you variable  speed return.

That isn't an option on the LT40 Standard, but a clever fellow could reconfigure the drumswitch wiring to make it so.

They must have changed it because my standard came with it. I used it till I got the hang of the board return.

Yes, they must have made a change since my mill was built.  I stand corrected.

How is the option selected on your mill?

You could put a toggle switch on the 2 wires and have the best of both worlds.

Yes, that's exactly what I was thinking of doing. There is a vacant hole on the front of the panel when you have the Dual Axis H bridge where you can put a switch.

Its only on the Dual Axis H bridge. My 2008 Super did not cone with dial acid, but I upgraded.  Haven't gotten around around to it as I have wireless remote ite, so I don't really care how fast it comes back.

That's a good idea. Once I got used to the board return I disabled it because I kept forgetting to turn the speed down after the return. But having an easy option to activate would be nice, especially when I have to back out of a log for whatever reason.

MagicMan -
 
A buddy of mine is a full time electrician at a production company nearby, he deals with controls, lasers, etc all the time.  One day while helping me fix something on the processor he was talking about  potentiometers and just called them "pots" or "pot" in the case of a single one for short.

So I read your previous post about the fast forward button and how it came to be  - good job by the way - well in reading the suggestion Brucer had and the potential problem that the wrong wiring could cause I came to the sudden conclusion that "Oh my MagicMan almost smoked his pot running his mill......"   The sudden visual gave me a good chuckle.  Sorry for "drifting" into the "weeds" there....  :D :D  Ok I will stop now.

Marty,

So I just got my LX450 Diesel home, and I'd like to add the variable speed on the return. To save me the effort of pulling a bunch of access panels and going on a mini search for these wires, could you give me a hint where to find them? I'd have guessed inside the Accuset 2 control panel, but looking at your picture leads me to believe they may hide elsewhere.

While you're helping. I love the solenoid that turns on my water (coolant..., lube,  whatever) , but the manual valve can't be reached when it's cutting, and I'm far to lazy to wander around the mill to shut it off when I don't want it. I don't suppose the power for that solenoid emanates from inside the Accuset panel does it? If not, and idea where I can most easily access the power wire feeding the solenoid that controls the flow so I can add a toggle switch to shut that sucker off manually as well?

Many thanks for the help,

Stu

Isn't that a switch you're seeing?  It looks like a light but I think that is due to the extreme perpendicular at which the photo was taken.

Include me as one who almost got whacked by a WoodMizer un-challegeable gotta get there return.  During a demo that almost became a demo-lition, of me.

In fairness to Orange, I would not want to slip n fall while pulling my Peterson back too hard/fast on the vertical cut, especially if it was set up with any kind of downhill-ness.  That blade does not look like something I'd wanna have pass "over" me.

Hello,
   The water valve is controlled by wire 19 and 20. 20 is black and is ground runs to the ground post in the box. 19 is red runs to # 2 of the power feed drum switch.

If your LX450 has Accuset 2 it would have the jumper wire to control the feed return with the pot. If it has Simple Setworks you will not be able to control the return.

If you have Accuset 2 then remove the front panel and the Dual Access H bridge will be hanging from the top. If you have the new command control option, I am not sure. There is nothing in the manual about this. Pretty new.

Hope this helps.
