Quick and easy Y-axis tensioners

I really liked what PsyKo had done to create belt tensioners here: http://www.shapeoko.com/forum/viewtopic.php?f=30&t=1608#p12474 The problem was that I didn't have the metal plates to create clamps or the extra length in my belts. So after giving it some thought I came up with this. I used the exis...

Re: How to unlock the Z-axis stepper motor?

Wow, that's a lot to think about. But, I've come up with an alternative that works almost as well. First, I found a new Grbl controller/sender that allows me to do much of what you've described in software: Grbl-Panel (https://github.com/gerritv/Grbl-Panel). I'm currently using a Surface Pro (1st se...

Re: How to unlock the Z-axis stepper motor?

DO NOT put a switch on the wire to the motor! Connecting and disconnecting the load while the power will fry the driver chip! They are well protected against shorts and over-current and overheating, but not against this. Thanks for the warning. When I tested to see which wire "released" the motor l...

Re: How to unlock the Z-axis stepper motor?

You can not unlock just one motor. The ENABLE inputs of all drivers are wired together and controlled by a single pin (D8). If you have limit switches and use work coordinate systems, it's counter-productive to move the machine manually anyway. Jog the Z axis instead (you can set the steps and spee...

That unlocks all the motors. I just want to unlock the z axis.

Re: GCodeTeleporter.com - Another Free Windows GCode Sender

Nice work. There's a lot to like here. I tried it out and here's some feedback: Current positions are showing blank (it seems you already are working on that, but that's a key function) I have to click the drop-down and select my baud rate every time I open the program. It would be nice if it just r...

How to unlock the Z-axis stepper motor?

I'd like a way to unlock/release the z-axis motor before and during cuts so I can fine-tune the z height. I'm using Grbl 0.9g and have set $1=255 to keep the steppers locked at all times. This setting to applies to all steppers. I cannot unlock just one motor/axis. I know I can put a switch in to di...

Re: HeeksCNC units

After some experimentation, I determined that Heeks is very particular about what file formats it can import properly. I tried SVG and DXF from Illustrator, Visio, and Inkscape. The only format that has worked so far is DXF from Inkscape. Even that has to be very specific. When saving, only check "u...

Re: PWM Speed Control - Will it work with gshield?

I suppose that explains why I'm getting higher RPM's. I don't claim to fully understand it, but it works for now.
