Some more experiments: -Printing the same hyperboloid off centre does not alter it's appearance, so it's not centre-specific. -Printing a set of cylinders show the waves nicely. The cylinders are all...

Ah, got it! It's the extruder heater. I tried printing a single small cylinder, and was watching it. Heater LED goes on - the diameter increases, heater LED goes off - it starts decreasing. With 20...

Yeah, PID controls it a lot more closely. In my opinion, PID should always be used for extruders. Glad I could help, even if indirectly. I'll add that to my iddy biddy knowledge tree.

Andy, What firmware do you use into the RAMPS? Marlin? Also, I would like to add a 25mm (I took the mesurement of the Sunon MC25101V1000UA99) fan for the J-Head as it seems recommended for PLA. I...

@ekaggrat Yes, but the problem is that when you do it like that (with the effector centered) errors in one carriage can compensate errors from other carriages, becoming into x and/or y errors and not...

Good spotting! I thought the defaults in marlin were set to pid already! Some cool reading and calbrating you could look at to make it even better: [reprap.org]

I find when it's calibrated properl it doen't overshoot the temperature by 10-20 degrees like it used to when heating up and also maintains temperature with less temperature swing. So its a bit better...

I've never overshot more than 6-7, usually about 3-4 on a high. Stable within +-2.

Thanks, sounds like I could easily do it with my drill press based on the descriptions.

The hardest thing was getting the ball end mill bit. I paid local auto mechanic tool truck price for my 1/2" bit, and my cost per screw is down to $1.50 each after three sets. :( Andy had much better...
