I put them on because it cost me $20 and I don’t need to brainsweat as much. My inductive switches made 1/2 a thou as well. More like .0003.

Also a point of annoyance - your controller may closed loop operation. Or the encoder may only drive the LCD.
The mechanism I use does not support closed loop - and you cannot do closed loop...

This is the control board I use for this.
So controlling spindle operation will be doable via analysis of your reversing switch.
This switch will most likely have a voltage or ground that is switched when you turn it. This will be...
So here is my analysis of whats going on so far:
1. Your Controller VI may not control the spindle at all. Nothing. It may only want to control the axis motion.
2. You have a standard...
Interesting. That is a 2.2KW closed loop BLDC drive.
X3 is motor drive power.
X7 is the hall effect sensor for the motor.
Are the X* connections marked on the main board?
It says X6...
That is much fancier than a KBIC. It probably has an integrated LCD for spindle speed.
Is optimum still in business? And any chance you can find a part number on this board?
I’m...
KBIC-125 (9433) DC Drives Chassis https://www.amazon.com/dp/B007ZQLJM0/ref=cm_sw_r_cp_api_i_6P3VCbMZS9BBP
It will look like this for the most part. Hear sink for the mosfets and this mounting...
I had some of these same experiences in my build. I used hybrid steppers if you haven’t done the purchasing yet.
Much quieter and I’m able to wire in an alarm setup so it works well in that...
So i do this with the c76 board from cnc4pc. But on a KBIC controller. On a g0704.
Chances are high that you have a KBIC clone controller inside the spindle control box.
If so, yes you can...
Single nuts unfortunately. The other main issue I have is that they don't have a wiper on them to wipe any chips away so you have to be super anal about guarding them.
SO. quick updates.
I made my first good parts this weekend. My commanded size on this part I made was .370...actual part was .37025. I'll live with that.
I have $3k total into this...
Whoo I am having a strange one here.
So - key data to help folks understand what I'm doing:
1. UCCNC Controller on a milling machine.
2. UCCNC post processor, also tried the Mach3 one and it...
Thank you most helpful. My data says 200khz
What is a practical max step number for the uc300eth? I’m mostly interested in quieter operation of my machine. i have about a 5:1 ratio so at 800 steps per rev I have about 4000 steps per inch. ...
What was the biggest challenge? I mean compared to him milling the ways off to use linear slides and such. And he has the new column already it looks like.
Not doubting you - you have done...
So odd note. I would finish the 0704 mostly stock and see if you can sell it. Why? If you are making your own column and using rails just go all the way and go full custom. Maybe order just the...
So a fun note - what happens when you add gussets to the existing column? Heck, you could almost capture the existing column within the i beam pocket and bolt it down.
Does anyone know the stock encoder pinout? Haven’t been able to find it.
Also I hate to add to this, but based on my research (and not experience) you might want a c6 screw for an almost 1 meter span.
Post a picture of your damaged board. I may have it from my conversion.
This is a really nice video sir.
So i ordered the conversion from Heavy Metal CNC oddly enough.
I liked some of the features, and I think the whole world must need something higher profit margin than these G0704 kits right now...
Yes - I mean closed loop steppers.
Great feedback sir - and the steppers I'm using are 3NM or 428oz/in. I meant to say quantity 2 not 2.3NM. Oddly I have heard that due to the closed loop...
Edited to add that I ordered my motors!
I’m going to be doing a post on the motor controller wiring and the control box soon.
Ordered some cheap optical home switches off ebay.
Does...
I’m very happy LinuxCNC is out there. It prevents price bullying on the part of the groups that sell control software to hobbyists. The second the price gets out of hand, LinuxCNC shows up to save...
I like the C76 setup from CNC4PC for the UC300 ETH. It has a lot of features, is similar in price to the Centroid stuff, and has its own builtin BOB.
Quick pics of starting my control layout and the rear down.
Hey everyone! First of all I wanted to say thanks for the inspiration and information to get this done! I don’t think I could do this without you all.
6 months ago I was fortunate enough to...
Where is the best place to get the wiring conduit with the fingers for the sides and the snap on front cover? I think a 1.5 x 1.5” would be ideal for my usage, or maybe a 1 x 1.
The only...
