dose anyone out there know what the rough settings would be for a adrians extruder setup.? for the firmware, https://reprap.org/forum/read.php?154,85588,85588#msg-85588 Sun, 07 Jun 2026 04:20:35 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?154,85588,92556#msg-92556 https://reprap.org/forum/read.php?154,85588,92556#msg-92556 -------------------------------------------------------

Yes. I've posted this several times before. Set e steps per mm to the calculated value based on your extruder. Then adjust the filament packing density ratio in the dimensions plug-in to get the correct feed length.]]> brnrd Skeinforge Mon, 01 Aug 2011 01:47:16 -0400 https://reprap.org/forum/read.php?154,85588,92544#msg-92544 https://reprap.org/forum/read.php?154,85588,92544#msg-92544 dissidence Skeinforge Sun, 31 Jul 2011 21:14:52 -0400 https://reprap.org/forum/read.php?154,85588,92541#msg-92541 https://reprap.org/forum/read.php?154,85588,92541#msg-92541 Max-Max Skeinforge Sun, 31 Jul 2011 20:15:55 -0400 https://reprap.org/forum/read.php?154,85588,85806#msg-85806 https://reprap.org/forum/read.php?154,85588,85806#msg-85806

Firstly download the latest Gen6 firmware and the Arduino with Sanguino from here [www.mendelfactory.com]
Make sure you get the correct firmware for your Mendel to correspond with the opto’s that you have.
Extract the Arduino and the Gen6 Zip files to a folder on your computer. Open Arduino click on Tools, go to board and select Sanguino.
Next go to Tools, Serial port and select the Com port for your Mendel
Now the fun part Click file, Open and find the FiveD_GCode_Interpreter.pde file. A new window will open
In the new window over at the top right is an arrow click it and select configuration. Scroll down until you get to a line of code that says
#define E0_STEPS_PER_MM 20.2 //Miocrostepping! Edited 20100715 @ EJE. 2.0
It is the 20.2 number we need to change.
Start Repsnapper, connect to your printer and heat up the nozzle to somewhere around 180-190C. While it is heating up get a ruler and a marker pen, measure from the top of the extruder block and make a mark on the filament at 150mm.
In Repsnapper in the Print tab where you set the temperature, set the speed slider to something slow like 75-100 and set the length to 100. To get the correct numbers use the arrow keys on your keyboard.
Click the extrude button and once it has stopped extruding measure to your mark. Mine moved 3mm so to calculate the right setting you need to do
100/3 which will give you 33.33 we went for a more conservative figure of 25
Now do 20.2*25 which should give you 505
Change the fire in Arduino to 505 save the change then go file, upload to I/O board. Arduino will say uploading, wait for it to say done.
Now run the test again making a new mark at 150mm up the filament, I ran it twice once at speed 100 and then at speed 75. I now had achieved a movement of 66mm so still some tweaking needed so do
505*100/66 which gave me 765
Change the number to this in Arduino and upload again to your I/O board,
Test again I was now getting 98mm of extrusion so did one more calculation of 765*100/98 to get 780.6 which I set in Arduino uploaded and ran the test twice more. I was now getting a perfect 100mm of extrusion. So I am now ready to start my first prints]]> NelsonRap Skeinforge Sat, 04 Jun 2011 17:02:36 -0400 https://reprap.org/forum/read.php?154,85588,85588#msg-85588 https://reprap.org/forum/read.php?154,85588,85588#msg-85588 dissidence Skeinforge Thu, 02 Jun 2011 23:05:38 -0400
