Re: TB6560 Stepper Driver Board

I am not familiar with the differences between the TB6560 and the TB6600 other then the number is 40 larger :mrgreen: I would assume the 6600 is a newer version and seems to be more expensive so my guess is that it is a better chip. That being said, in my opinion, buying electronics direct from chin...

Re: TB6560 Stepper Driver Board

I am using individual TB6560 boards without any issues so far. I do not have an large # of hours logged on the machine but it has been solid for me so far. Only issue I had last time was with my homing switches not tripping correctly which is unrelated to the stepper drivers. Take a look the electri...

Re: Polycarbonate V-wheels! :D

Yeah, I don't know why OpenBuilds say that PC is better than POM, because it isn't, but you'll also notice that those V-wheels are for V-slot only -- they don't have a V groove at all. I agree with the comments here that delrin is better then polycarbonate -- at least with the delrin and polycarbon...

Re: Tb6560, worth it?

Are you talking $10 per driver or $10 total. $10 total seems too cheap. $10 per driver (you would need 4 drivers) sounds more reasonable. I used single axis tb6560 controllers from e-bay. I went with the single axis as I figured it would be inexpensive to replace one drive if it went bad on me. Not ...

Re: Touch off issues - I'm sure I'm doing something wrong

I hate to admit I did the exact same thing on my first try - only with a sharpie pen. Mashed the felt tip quite well! Glad you got it figured out!

Re: project exceeds length of shapeoko 2 (Y axis)

Since the Shapeoko 2 full kit has a 11.5" cutting limitation, what's the best way to cut a sign that is longer, say 16"? I suspect that I need to divide the project in half and make two jobs. I'm just concerned about the zeroing in for the second job. Any tips or tricks? I have not used it yet, but...

Re: Pictures of finished machines

Glad to see you're not experiencing any interference, which the concern of has kept me from doing anything similar. Just as a another "data point" I also run the power for the router through the drag chain with the stepper and limit switch wires and have not had any issues as of yet with it. Steppe...

Re: Makita RT0701C Mounting Bracket with Dust Boot

Just FYI in case you missed it, there is now a custom 1/8" collet for a the RT0701C. See this post for details http://www.shapeoko.com/forum/viewtopic.php?f=8&t=3445&start=40#p26731 Personally, I am currently using a collet adapter from MLCS: http://www.mlcswoodworking.com/shopsite_sc/store/html/sma...

Re: Troubleshooting v-wheel on x axis

When the V-wheels sit in the same position for a while, they deform slightly, which creates a slight bump every revolution. When you run the machine, or let it stand disassembled for a while, the acetal slowly returns to its initial shape, and the bump goes away. This can happen if you have the V-w...

Re: Limit Switches - A Poll

I had no problems at all installing limit switches at end of travel for both homing and limit. Used inexpensive ones from here http://www.circuitspecialists.com/66-4010.html I am using linuxCNC with shielded cable and the shield tied to ground on the controller end. I like how this works with with l...
