Re: Just in time for Halloween!

Not a bad idea. Is it really flat? :) I can't say if it is perfectly flat, as I have no way to measure that. I will say that it lies completely flat on my kitchen table, which is flat enough for me. Its complete flatness isn't a major concern for me, as I am budget limited and don't want to have to...

Re: Just in time for Halloween!

I've been trying to figure out a way to do similar. Would the amount of wood you have there allow for warping over time? Good question. The same question could be asked about the stock S3. In both cases (stock and Frank n oko) I applied a sealant coat of three layers of lacquer in hopes of reducing...

Just in time for Halloween!

thumb_P1010950_1024.jpg Just in time for halloween, I present to you the Frank-n-oko! I was having troubles with the levelness of the stock S3 bed. I had runout in the neighborhood of 0.05". It was higher in the front and cupped in the middle. This was an early machine (s/n 074). It might have been...

Re: Lissen to the Music, my stepper motors,my shapeoko3!!!

When troubleshooting, I tend to look at power supplies and infrastructure first. I am wondering if the system power supply is in trouble. If you're adventuresome you could open it up and test it with a voltmeter.

Re: Z Axis Backwards

In looking at Winston's video, it appears that all of my motors are cabled backwards..... My motors are red/green/black/blue from left to right when looking at the board, and his are blue/black/green/red/.... If I look at my X and Z axis connectors on the controller, with wires towards the rear, my...

Re: My S3 limit switches, beginning

Another possible option (if I understand things) would be to input machine dimensions slightly less than the travel area of the switches for soft limits. Will; I'm guessing you are talking about the grbl commands $130 thru $132 (x,y,z max travel, mm)? That will be a good option once I can run the '...

Re: My S3 limit switches, beginning

arent the springs meant to prevent that or am i missing something? otherwise powering off would drop spindle as well I am using a stock Dewalt router and no dust shoe. When the drivers are disengaged, the spindle settles a half inch to 3/4 inch. It doesn't crash all the way. This was enough to drop...

Re: My S3 limit switches, beginning

For the brave, here is my schematic. The parts values were whatever I could find on my bench. P1010693.jpeg I discovered something that is a potential problem with the controller action. When I hit the limit, the controller immediately disconnects the motor drivers and reengages them several seconds...

My S3 limit switches, beginning

As I built my S3, I planned for limit switches. Before I begin I should say I've been busy with work and only implemented the limit switch on the Y axis beam. As TomDChi and LTEPM have stated elsewhere, I didn't want a lot of flying wires wires. So I installed two magnets on each end of the beam and...
