It is a ER11 colet with 8mm shaft, I removed the shaft from the outrunner and installed the ER11. It takes some minor mods like grooving the colet for the retainer clips but seems to work well

could you elaborate on the conversion procedures for fitting the ER-11 shaft into the outrunner motor? I'm not yet familiar with the outrunners but you have made good use of it as a spindle.

Thanks!

I must ask. Do you have the PCB schematics for the bob and Vreg?

The outrunner has an 8mm shaft and the shaft of the ER11 is also 8mm
You must carefully disasemble the out runner and press out the shaft
Then place a grove in the ER11 like the outrunner shaft
Press in the ER11 and assemble the motor.

Yes I have them in PDF format I just need to find a way to get them to you, pm me a email addy and I will send them your way

Sent. Thx

Just curious if you knew why they used a 470pf cap on pin 7 I have seen 100pf and 330pf used but not 470.

Not sure myself and that's why I followed the data sheet and used a 330pf i did a mix of what they used and what the data sheet required. I also used only 10 x 1 ohm resisters instead of 12 to limit the driver to 2.5 amps

I will put them PCB lay outs together for ya after dinner

[NSR_CIVIC]

That works. I am having a hell of a time finding 330pf in my stuff.. I was @radio shack today and didn't even think about it...

Well I spent the last 3 hrs tracing circuits on the 4 axis board and I still can't figure out why my x axis is screwy so I pulled the 6560 chip off and I'm gonna stick another one in. If that dont fix it ill start collecting materials to etch some pcbs. If it does fix it ill see if I can't mill out the pcbs either way I'm gonna ditch the poorly designed board for one that's more usable and fixable...

Got Ur email. Do u have the bom for the breakout board?
I have not opened the files yet cuz I mainly use my phone for forum and email so if their in there just ignore me.. lolz

Hold off on the bob just for now I may change it do to a ground issue on 1 of the ic's will let you know ASAP

[NSR_CIVIC]

no problem. i believe you had said you were etching yours? im trying to find a way of converting it to an nc file to machine it. any ideas?

[RMHCNC]

I use NC files for my laser and use Inkscape and a modified version of gcode tools plug in.
If ya need something I will try and find the link that will explain the process and where to get the files needed.
My laser cnc runs Grbl 8.0 on a arduino nano and 2 easydrivers

[RMHCNC]

That program is a great little tool for fast simple boards but the output options are garbage.
Can't beat free though lol

[RMHCNC]

Well with all the trouble I'm having with the bob I decided to just order a $14 eBay job and will continue to work on its design later on. Don't want to risk my pc at the moment. Everything works well when I test the drivers with my arduino nano for controlling the step dir and enable so why waist time lol

[NSR_CIVIC]

That works. I thought about ordering one too. Making one is almost pointless when the price is so low.

You got it man, the only thing that sucks is the wait time.
It looks to be the same manufacturer as the CNC board that failed on me so I hope the thing works lol.

Your project and the 8mm shafted outrunner has had my mind thinking for the past few days on a different approach to a "personal" cheap ATC. Rather than switching the tool itself out and everything involved with that (since the supporting hardware and specific tool spindle requirements generally cost many time more than the average hobby cnc setup many times over)

Why not simply run 2, 3 or even 4 of these motors and keep each loaded with it's own dedicated tool. And rotate the entire motors assembly tool and all into task. I have nothing firmly in mind but perhaps a round rotating plate with angled mounts for each motor. Not as elegant as a ATC or offering as many cuttings choices loaded up, but far more affordable and far simpler for us hobby level guys.

I suppose the biggest issues would be speed controller wiring or rather how to deal with the rotating motors and the connections to the setup........

The outrunners are just nice and compact and not in the 3000 dollor price range each, not even close.

[RMHCNC]

That is just to funny my friend because that's what I have in mind. Further down the road if this setup works well then I will use it to build version 2.

Great minds think alike they say....lol.
