Re: Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level - 10 years ago
Quotedavidf01 So I took my extruder apart and checked to make sure everything looked like there was no damage. It looked good. I adjusted the Vref down to about 65 and the extruder motor starts jerking back and forth when it is trying to feed the filament, is that normal? I did a test and extruded 50mm of filament and it extruded about 40mm so I'm about 10mm off so far. I also did a test printby tjnamtiw - Delta Machines

Quotebuilt350camaro I have a silly question. When I home everything and then move my Y axis a negative amount it moves the bed toward the front. is that intended? The endstop is at the back like it is built. Everything seems to print fine just checking to see. There are no silly questions at this point, B350C. Are you using the LCD screen add-on to move and home? When I use mine, it won't lby tjnamtiw - Prusa i3 and variants

[email protected] Thanks for the help guys I have my print centered now. Though my Y axis seems to have changed - and + directions and I have no clue why. My X axis stop was also not in the right spot. But it is centered now I need to change the print size down to 180x180 and I am also going to do a rework of my bed.

I spent this morning dialing in the extruder rate AGAIN after taking apart my feeder and removing the interference between the feed gear and the extruder motor endbell. I am now extruding exactly 100mm when I tell it to and the parts look great HOWEVER to do this, my Estep for the extruder is all the way down to 26!!!!! There must be somewhere else perhaps in the configuration file where somethby tjnamtiw - Prusa i3 and variants

Quotekn4ud [email protected] Can anyone shed some light on how I center my bed better? It acts like I need to mount the endstop farther back but how? Maybe these pictures will help: It looks like your end stop is hitting the bed and not the bearing retainer under the bed. I t should be laying almost flat. Also the mount is on backwards.

Well, after two days of pulling what's left of my hair out, I think I finally solved my inconsistent filament feed rate. I had the dreaded click-click-click sound today while feeding, which could mean a number of things, from what I've read. Anything from 'wet' PLA, to not enough power to the extruder motor, to misalignment of the filament into the hot end, to not enough heat in the hot end, adby tjnamtiw - Prusa i3 and variants

The kind folks at FT came through today in the mail with not only a new thermistor, which was bad, but an ENTIRE NEW HOT END! I'm up and running at last! As an easy project to wow the Mrs. I printed a couple of snowflakes at various scales. They all came out looking good BUT 'overstuffed' so I knew I needed to check my extruder feed rate.

Another thing that I notice when I look at the fit of the bearings into the X carriage is that the length of the opening is much shorter than the length of the bearing. No amount of pushing will get them in there! Back to the Dremel! I also found that the spacing between the two holes in the X carriage used to mount the hot end are too close together.
