I have a question guys

I have an KL8060 stepper driver and the red and green LEDS are on constantly
Any idea what it could be.

I think I have narrowed it down to the motor I have 8 wires tied in pairs
Z Axis 906 ozin
yellow/black
white/brown
orange/green
red/blue


The yellow/black tones with all but the red/blue
Is this right or do I have this wired wrong?

Thank you for the help in advance

This pairing for A coil
Blue to yellow
Red to green

This pairing for B coil
Brown to orange
Black to white

Hi Hoss, I had purchased all your DVD's, did the G0704 conversion with treadmill motor...it all works great. One thing I still need is a surface grinder.

What do you recommend?

I remember you did something with a angle grinder on your X2 with a modified angle grinder. You did some mods to the bearings if I remember right. How well did that work?

I want to make my own 123 block and some other little projects, but need a decent surface grinder.

Thanks
David

I got it and it worked.

Is there an already made gcode to test the machine with for the first time?

Yes, open up the Load GCode window on the first screen of Mach. Look in samples, pick 1. Most choose the Roadrunner for some reason.

Well you could make a right angle attachment for the g0704 like I did that could hold a grinding wheel, the attachment can rotate towards the front.

Then pickup a mag chuck like the one I used on the X2.

But craigs list is a good idea to find a used surface grinder.
Grizzly sells one for not a bad price.

Ok, the mag chuck is what I was looking for too, and the right price so I bought it.

Now where would I get the drawings for the right angle drive?

Thanks Hoss

Thanks, I'll put those together on a disc and send them along with the chuck.

I have made all the parts for the Z axis direct drive with the larger coupling. My question though is this: I can't find the info on the DVD about whether or not I remove one of the jam nuts on the top of the Z axis lead screw to make room for the coupling. It looks like I would have to, but want to verify. Also, how would one go about removing it? Some kind of spanner? Can I use something common like a crescent wrench or Channel Locks?

In reading thru I saw this older thread where you were selling your treadmill motor and linear rails.

I seem to remember you once talked about modifying yours for rails, just changed your mind or did not see much advantage to the mod?

I am still using my treadmill motor, just can not rigid tap with it. Bought a compression tapping head.

I am going to change my g0704 from dove tails to linear rails. I will be trying out 25mm rails and blocks. I have 35mm ones too but they are way too big, no room to do those.

I did some testing today with the 25mm blocks and rails. The longest rail will be 24 inches. With the room available I can use two blocks per rail but the blocks will be touching to allow full travel. I put my test indicator at the end of the rail with it extended the full 24 inches and applied 30 lbs of weight. The rail deflected .0004, to me that is acceptable. These are high preload and N rating, they are supposed to be very good.

Now the saddle plate I am going to have to do away with and plan on using a .75 steel plate. The x bearing blocks will be mounted inverted on the top of the plate with the rails mounted on the bottom of the table after I mill the half dove tails off. Then the Y blocks will be mounted on the bottom of the plate with the rails mounted to the mill stand. I will be making a new Y extension block that will attach to the mill stand, then both the mill stand and extension block will be attached to a 1 in thick steel plate then milled together to make the area for the rails to mount to for the Y axis.

It should, if I do it accurately, make for better accuracy and less stepper load with better stepper efficiency.

Linear Rails or big treadmill motor anyone?

Remove one of the nuts so you can jam the pulley with the remaining nut.
A spanner is best but you can knock it loose with a hammer and blunt tool like an old screwdriver.

Sounds like a plan, I sold all those parts already.
Only have a very heavy duty pair of linear rails left that I was going to use for a lathe Z axis.

I'm looking into linear rails on my G0704 Z Axis. I would rather not put out that much cash for an upgrade, but I cannot get my damn Z axis gib to fit anymore. I removed the column to machine some simple oil channels in the headstock mounting plate, and now I can't get the gib to go more than 3/4 of the way in. No other mods, no screws attached, no fittings, nothing but cast iron (no mods to column or any dovetails either). X and Y fit perfect, but Z magically no longer fits. Tried every possible combination of installation, I am truly stumped.

Look at the little brass nibs in the holes that the lock handles press against the dovetail. had one of mine stuck protruding a bit and it prevented the gib from fully inserting.

[mrosso]

Hoss, thanks for the quick reply! That was the first thing I looked for, but all of the lock handles,screws, etc. were taken off prior to putting in the oil channels. Double-checked to make sure the brass pins didn't get stuck in there as well. You can see right through the dovetail where the lock pins used to be.

[hoss2006]

Check the gib strip on a flat surface for any bowing, sure no burrs or raised edges from machining the oil grooves, any dinged edges, sure the strip is burr free and as originally installed.
Doesn't take much of an imperfection to affect it's complete insertion.

I’m interested in the linear rail mod that Scott from Benchtop Precision did. Does anyone know what the weight of the bare column and z slide are?

I also found Hwin block and rail here https://www.amazon.com/HIWIN-HGH15CA...6493029&sr=8-4. Seems much less expensive than Automation4less. Too good to be true?

Any particular reason you are asking this in my thread? You've already asked about those in another thread.
In future, addressing questions to me in my thread about my projects or opinion will get answered promptly, thanks.

Is it my imagination or does this thread get periodically locked and then unlocked a few days later? What's up with that?
