Anet A8 with Titan Aero extruder print issues.

by AdrianW

His all,

I need some help. I am getting this lumps that show up. It looks like I'm printing great until the effector needs to start retracting and moving to a different spot. I am printing with PETG at 240deg C, E3D Titan Aero extruder, Anet A8.

Nozzle and bed temperature

by rafaelc97

I have an issue with temperatures, my printer does not "obey" the temperatures set in the slic3r for neither the nozzle nor the bed. No matter how I change the settings, it always goes to 230°C and 65°C. I think it has something to do with the Marlin firmware, however, I don't know how to change it. I used the "M303 E0 S230 C8" and "M303 E-1 S90 C8" commands on g-code, to calibrate the PID, maybe it has something to do with it.

Also, sorry for any grammar mistakes, english is not my first language :/

3D printer heating issues-- showing at temp, 30 degrees less

by Monomethylhydrazine

I'm having issues with my e3D v6 old style heater block with this thermistor: https://gulfcoast-robotics.com/products/2017-version-hex-screw-in-m3-ntc3950-100k-thermistor-3d-printer-extruder-hotend

when it claims to be at 200 Celsius, it is read to be at ~160-170 on a multimeter thermistor. In firmware, I ran PID autotune, changed temp sensor to Marlin 11, and have raised the max temp to 300 like the thermistor can reach. How can I solve this?

A Little Gcode Help Plase

by MakeItMakeItMakeIt

UPDATE: Thank You valand70 and Numien for your replies. I'm set now!
Didn't know/see the diff between G28 and G1 as I really haven't played a lot with it. I just today got kinda curious.
I've got the End Gcode sorted, and am looking into the file created by Cura to see just where my M117 is being overwritten.
Still have much to learn and looking forward to it.
Very much appreciated! You all ROCK!

Hey All,

I'm having some difficulties making my Start and End Gcode do what I want, and can't figure out why.

My Start Gcode:

G21 ; metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with fan off
G28 Y0 ;Y Home
G28 X0 ;X Home
G28 Z0 ;Z Home
G1 Z15.0 F6000 ;Move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of filament
G92 E0 ;zero the extruded length again
M117 Rippin it...;put message on screen

The problem is this: the M117 line DOESN'T display the message I want: it just says "Printing..."

My End Gcode:

M104 S0 ;extruder heater off
M140 S0 ;hot bed off
G91 ;relative positioning
G1 E-1 F300
G90 ;absolute positioning
G28 X0
G28 Y180
M84
M117 Finished

It displays the M117"Finished" line bit DOESN'T move the bed forward to the Y180 absolute position.

Can someone help me understand why it's not doing what I'm asking?

Am I correct with my commands or do I have something wrong?

Thanks in advance. :-)
