Re: PETG eats the glassbed, what to do? - 7 years ago

Quotedlc60 Wow, this just never happens. I wonder where our processes differ? DLC Very easy thing. Tape and hair-spray protect your glass from PETG bits it. If you don't use tape or hair-spray, you realize PETG doesn't need it to stick on glass. But realize it's too hard to remove from glass. After realize too sticky PETG, don't try to remove by scraper or pull/push PETG from glass. If you do,

I don't know why everybody worry of removing PETG from print bed. If you use BOROSILICATE GLASS bed, only gently wash under the water after cool down. It't too easy to remove, no need of scraper or another tool, or stick glue, tapes. Only pick and pull by your finger!

Quotekrakow2000 Got A8 with e3d v6 and need help with two things: 1. Can anyone share part of Marlin code for Piezo20 work?? Got Marlin 1.1.8 with Hall Sensor but need change to Piezo20 and don't know what to change in code. 2. Wha X mount you use for Piezo20 and A8 (or other Prusa i3 clone)?? Found couple in thingiverse for example but Piezo20 mount is too wide. Anyone can help? My Geeetech

Mr.tekkydave, I did not know "baby stepping". I will modify Marlin and use it! THank you!

Quotetekkydave I dont believe the above G29 commands (G29 S2, G29, G29 S1) will work on Marlin as the G29 gcode implementation is different. The same operations are possible as in the last post but the parameters are different and saving is to EPROM not SD card. I used Marlin up till about a year ago when I switched to the Duet. I wouldnt ever go back now. Marlin has three types of bed leveling

Re: Precision Piezo Z-probe Now available. - 7 years ago

Quotetekkydave How many points does it probe during the bed levelling. Try reducing it to 9 points (3x3). Unless your bed is very irregular 9 is sufficient. I reduce my fan from 100% to 75% during probing. It reduces the vibration enough to not interfere with probing. I use a Duet WiFi which runs the RepRapFirmware (RRF). The G29 behaviour is different for RRF to Marlin. I run the bed mesh level

QuoteDjDemonD One solution depending on your controller might be to use a controllable fan output for hotend fan and then you can turn the fan off during probing. If you are probing cold or at an intermediate temperature such as 130 deg the heat creep (depending on your hotend) should be little or no problem. Mr.Simon, thank you good advice! But I'm using UBL system on Marlin, and it takes about

3. Pushing the Teflon tube too far Send filaments with Teflon tube from extruder to hot end. This Teflon tube is fixed to the extruder so that it can not be pulled out with a one-touch connector. After that, it passed through the piezo sensor. The one-touch connector fixes the Teflon tube only in one direction, but if it pushes in excessively, restrains the hot end and hinders the piezo sensor fr

2. Vibration of throat cooling fan Piezo sensor is attached to the opposite side of the throat following nozzle, hot end. The throat has a cooling fan, which prevents the heat of the hot end from being transmitted to the piezo sensor side. If the blade of the cooling fan is scratched or the bearing deteriorates, the fan vibrates. This vibration prevents the piezo sensor from detecting the pressur

Re: Precision Piezo Z-probe Now available. - 7 years ago

Precision piezo is extremely high performance. However, since it is very sensitive, handling methods that have not been a problem until then will cause performance degradation. Here are some handling deficiencies I experienced. I hope this will be help someone as caution of handling Precision piezo. 1. Restraint of hot end heater and sensor wiring Wiring is connected to the hot end heater and se
