Been reading through the thread here and find it has progressed nicely. I initially setup the LMS spindle control board but was interested in more info here. I had a couple of questions I didn't see...

That's great info and might help those looking for info on this board. I know when I looked, there wasn't much around. I purchased a MachTach and will be installing that on the mill to monitor the...

I have the SCB setup now and running thru Mach3. Here are some screenshots of my configuration. I'm sure each setup will be different but a good baseline to start. This is with the Enthernet...

I did get a chance to test a few different speeds from Mach3 to the spindle and they did correlate for my setup. Now I only tried 5 steps (300, 500, 700, 1000 & 1700). Give or take +/- 10-30 RPM's,...

Yes, I have it setup and working now. I will post more info, screenshots on the addition of the SCB later this week. So far the board, for $99, works as designed for my setup. I can now turn On/Off...

Success. I now have the LMS SCB running from Mach3 and variable speed, on and off. Give me a few days and I'll do some screenshots of the Mach3 setup, the steps I did and maybe a small camera video...

I had some time today to rewire the SCB from the simple test to the G540. All set wiring and moved on to the Mach3 setup. Unfortunately I had an issue trying to get the Smoothstepper recognized on...

I was reading thru the thread and was wondering how these work with the G540? Connection? I would be interested in the 1100w for a Grizzly (0619) SX3. Currently doing a write-up on the LMS Spindle...

Wiring:

Part1. Simple wiring.

Last night I had some time to wire up the board using the Simple Wiring to for testing. Following the directions, I made a the two jumper wires from Start/Stop to...

I will break down the install of the LMS Spindle Control into 3 parts (Mount, Wiring and Mach3).

MOUNT:

The first step was to mount the SCB (Spindle Control Board) to my SX3. The hardest part...

OK. Not sure what you mean by the above "if you have it setup"? I do not have the spindle control setup yet or installed but will be working on it the next few days. If your talking about just a non...

Yes, this is for SX3. I do see that they have an SX3 for 240v version now. That is something new and maybe they will do an X3 someday soon.

Matt

Not yet but it is on my next TODO. I will post the steps I used to install mine (build link) and if anyone needs more description/pics on something in particular, just let me know. I think I found a...

Sure thing. I had to step back and just finished installing my panels for my 8020/Enclosure. Talk about working backwards. The cost of the plastic had me reconfiguring my 8020 to fit some smaller...

OK. From what I remember on these switches is that they can be setup either NO or NC in the initial setup. Then as the table's axis moves and "switches" them to open or closed and stops. I use these...

LMS Spindle Control Board install coming:

Well, I don't think I ever wanted to ever cut at these limits but setup just to see what travels I could get. Obviously, limit block size can be adjustable to get balance of stability and travel.

Received the LMS Spindle Controller this past Friday. I will add my install to the build link I created for CNC'ing the SX3.

The install is with a G540 with 110v and I'll try to see what the...

Update: ...on it's way...

I have a G540 connected to an SX3 and will order one tomorrow and then do a write w/pics to share. A giveback for all the help this forum has provided me. If anyone is...

OK, I was asked for more pics of how I setup my x&y limits. I do have the extended x&y so your results may vary. Let me know if something isn't clear and I will take an exact image with measure if...

Yes, I would like to see any info on this as well. Great to hear it works... Matt

Those questions could probably be found or answered better on the CNCFusion forum. I think someone in the forums here ad the pulley/belt part no's too.

Thanks, Matt

A very nice controller box setup you have now. I dealt with CNCRouterParts in the past for my Joe's 4x4 and had great service.

Interested to hear how the X3 spindle speed controller works for...

~that wasn't used but is for removing the ballscrews if you ever need to.



~that wasn't included in my kit. All the parts to remount the Z(mount blocks etc...) came from the original machine...

~Sure thing.
I bought the kit over at Automation Technology Inc

Specs:
G540 4-Axis kit(110V/220VAC):
1 pcs G540 4 axis Stepper Driver with 4pcs DB9 connectors
1 pcs NEMA34 906 oz-in Stepper...

~Hello. Yes, the Grizzly SX3 was around $1700 to my door. That is a big difference in pricing.



~Unfortunately, I went with stepper motors so I wouldn't be able to tell you the difference...

OK, after getting sidetrack with my other hobby (Home Automation) and building a FreeNAS box, I'm back on the CNC Mill. I left off with having to wire up the Home/Limits for the X, Y, & Z axis. So...

Sorry for the delay with getting your answer back. I got X,Y,Z moving after some debugging of my controller, Mach3, e-SS and the G540.

The Z-Axis with strut attached can get as close as 2.25"....

Thanks Bob.

Once I wire up the steppers and get it moving (argg, by hand stinks), I'll give you that info.

Limits and Stepper wiring with EZ-G540 connectors as the next steps...

Matt

My controller box is almost finished. One last piece is to wire up the limits to the G540 through the DB9 connector.

Here are some images showing how I wired up the controller box. I had some...
