Geeetech G2s Printer Kit Review

[Roxy]

* Ignore the autolevel feature for now - the printed guide for the probe can be too tight (or loose), and cause a head crash on autolevel.

I can certainly see why you say that. There are a number of issues with the Auto Bed Leveling. First, when I gave it a G29 command it moved halfway down and then started moving super slow in a sideways motion. I was wondering what in the world was going on. Looking at the code, I think I understand why that is. Who ever warmed over Marlin for this printer needed to provide a way for somebody to reach in and manually let down the Allen Key Z-Probe.

But come on people... This is totally lame. It would be just as easy to use the LCD Panel's switch to say the probe is down (and at the end, back up) rather than doing something totally Mickey Mouse like that. And as far as the probe goes, I ended up redesigning the Spider because the Allen Key is too far from the switch. The switch starts to exert a torque on the Allen Key and makes it bind in the hole that it goes through. Instead, I set it up with a piece of stiff coat hanger wire immediately next to the micro-switch. That seems to be much better. But once again, there is no way to know because they used such an old version of Marlin the M48 command is not in it. I'll know soon what the repeat-ability of my setup is. I'll probably add the wait for the LCD Panel switch in the G29 at the same time.

Here is the modified Effector. It seems to work well. But I've been looking at mounting a servo on it so I can kick down a probe leg instead of this manual stuff. I think I can use either the X-Min or Y-Min connector to drive the servo.

UPDATE:
I pretty much have the G29 working the way I want it. But I need to cross over the Topographical map stuff. And the M48 is going to be harder to get going than I realized. On Delta printers the X, Y & Z axis don't always refer to the Cartesian coordinates. I have to rework the M48 so Delta's don't go crazy. I suspect you are going to want the updated G29 when I get it done.
