Depending on the downward force of the test indicator tip, I'm not even sure how well that works. There is enough flex in the spider that I'm surprised people don't have problems with large asymmetrical prints tilting the bed just from uneven weight distribution...

I ran into a similar problem with mine when I tried to re-level it recently. The problem turned out to be the corner bed clamps. I frequently remove the glass to get stuck prints loose so I don't distort the spider. I make a point of unscrewing the clamps counterclockwise, and then twisting them bac...

Well, I got my new drive from MakerGear, and installed it last night. Once I had the old one off, I could see the problem. Because the drive gear was too far back, probably combined with twisting of the bearing due to the offset support, the filament had been pushed forward inside. It wore a large g...

One thing I've noticed recently is that even with the extruder fan running until the V4 cools down to 50C, the PLA I am using continues to melt a bit. After everything cools down, instead of seeing the full width of the filament going down into the hot end, it's often necked down to a much thinner w...

One thing you may not be aware of is that the V4 hot end has a necked down section between the hot-end body and the clamping section. I assume this is to minimize heat loss to the mounting clamp: V4 Hot End.jpg Unless the mount for the hot end gets too hot for other components attached to it, I woul...

That's the plan after I get some polycarbonate & get it printing nicely. There seems to be an availability issue with black 1.75mm PC at the moment. Amazon is out of stock on ePC, and Polymaker is out of stock on just about all flavors of PC-Max & PC-Plus. I'm still trying to decide which one I woul...

While looking at sthone's drive design, I also ran across this one: https://www.thingiverse.com/thing:1261678 It's meant to work with the standard fan configuration, which I would like to keep. What it's missing is the springs that stone used, but I can fix that easy enough. I'm thinking that using ...

That was my suspicion. I figured the feed failure was the results of some combination of three things: 1) too much drag from the spool, 2) too little traction in the drive, and/or 3) too much resistance going through the extruder. I did several things: 1) I tightened up the drive tension 1/4 turn 2)...

Well, that helped, but about a half dozen small prints later, and it appears to be slipping again. After getting some ratty areas in a few prints, I increased the tension a bit, and that would help for a while, and then it would skip again. Now it will start a print, and after about 15 minutes, noth...

Yeah, the Gizmodorks stuff hasn't gotten very good reviews. What sort of build plate and/or treatment have you used with polycarbonate? I don't want to have redo my print bed & re-level & zero unless I have to. I've had good luck with hairspray on the glass side of my factory build plate, and with g...
