Been up against a wall with Marlin extruding February 18, 2012 12:33AM |

Hey everyone. Finally got my prusa printing, it just needs to be calibrated now.
Ive got Arduino 0022 with Marlin firmware, going to post the config below. Im using RAMPS 1.3 with opto endstops.
My problem is no matter what I change the steps_per_mm setting, every time I try to extrude 30mm, I end up getting 18-22.
DEFAULT_AXIS_STEPS_PER_UNIT {63.4149, 63.4149, 933.3333, 2224}
Ive changed it everywhere from 700 to 3200, no change, right now its 933.3333. So I ask people who know coding heh.
If I screwed up somewhere else please let me know.
My X and Y axis are pretty spot on, need to fine tune the Z axis, but right now the extruder is holding me up pretty good.

The parameters are in order of X, Y, Z, E. If I read your post correctly you are changing Z not E. What do you get returned from an M503 command (show current settings)? I believe you currently have the steps per unit for the extruder at 2224. You can try varying the parameters with an M92 command - M92 E650 would match my settings for extruder. Once you have dialed it in, use M500 to store those settings in EEPROM.
Look at the main file in the Marlin package for all the G and M codes that Marlin understands.

Hah, I dont know how to initiate a M503 or any other command. My experience goes far enough to press buttons in pronterface.
Would I have to open the gcode file to input the M commands?
I changed the XY and Z values as well as the extruder values. I kept in mind it was in xyze format, but theres a real possibility I got stuff backwards.

Ran through everything again.
Heres my current settings:
#define DEFAULT_AXIS_STEPS_PER_UNIT {64.7091, 64.1202, 2305.6769, 3579.3991}
With the settings I posted earlier, I did another calibration of all motors. XYZ is spot on now, within about 1%.
I got a measurement of 18.64 out of a requested 30mm, so I did 2224/18.64*30= 3579.3991. I then measured the 3579 value, and out of 30mm, I get 16.70mm. My next step would be to go up to 6430, but this has been the loop im in, If I go back to 700, im still at like 18mm lol.
Also tried setting slic3r to 2.5mm dia or 3.5 dia to try and bypass the extruder problem. 3.5 gets a little more plastic extruded. Also the extrusion multiplier set at 1.5 doesnt seem any different than 1.

In Pronterface, below the dialog window to the right side there is an input box and a Send button. Assuming you've connected to the printer and saw legible text (even if it's meaningless to you right now) show up in that dialog window, just type (I think capitalization is needed) M503 and hit the Send button. More text should appear, mostly lines that start with echo: and then show you the M-codes you can adjust without recompiling and their current values. For example, you might see M203 X800.00 Y800.00 Z2.50 E45.00 telling you those max feedrates. If you only want to change the E value, in the input box type M203 E20 and hit the Send button, to slow down the max extruder feedrate.
If your g-code tells the firmware to extrude above the max rate, you only get the max rate. Try adjusting the parameters real time instead of recompiling the firmware, and once you have them dialed in, send an M500 to store them in EEPROM. FWIW, my steps per unit for E using a Greg's Wades extruder and a bolt I hobbed myself poorly, is only 650.
Trust me, you REALLY want to get this right in the firmware instead of compensating with Slic3r, Skeinforge, Repsnapper or other software, because otherwise you will be constantly chasing other problems.

First, I want to thank you for your help so far and in the future heh.
Ok, here is the text in pronterface:

I sent M503 and waited 2 minutes, then tried again and disconnected. In between attempts I moves the X axis just to see if it was frozen, everything was fine. Im not worried about the SD fail, its not hooked up.
Another question is should I mess around with the feedrate, when its the total feed length that refuses to be corrected?
Im pretty sure my math was right, I just cant seem to find a reason that the steps per mm setting isnt taking for the extruder. Its fine for the other motors, altering the value alters the real movements.
I want to clarify, I am familiar with code, just not coding
I can read what should be the setting for what, especially with how well commented Marlin firmware is, the advanced settings are a bit beyond me, but thats for the future.
Im only messing around with Slic3r settings to hopefully give me an idea of what im screwing up with the firmware.
Im 95% sure that I have a .5mm nozzle size, I got it months ago and dont have a way to check it now, even though that wouldnt have a bearing on the firmware issues.

SENDING:M503
Disconnected.
I sent M503 and waited 2 minutes, then tried again and disconnected. In between attempts I moves the X axis just to see if it was frozen, everything was fine. Im not worried about the SD fail, its not hooked up.
Another question is should I mess around with the feedrate, when its the total feed length that refuses to be corrected?
Im pretty sure my math was right, I just cant seem to find a reason that the steps per mm setting isnt taking for the extruder. Its fine for the other motors, altering the value alters the real movements.
I want to clarify, I am familiar with code, just not coding
I can read what should be the setting for what, especially with how well commented Marlin firmware is, the advanced settings are a bit beyond me, but thats for the future.
Im only messing around with Slic3r settings to hopefully give me an idea of what im screwing up with the firmware.
Im 95% sure that I have a .5mm nozzle size, I got it months ago and dont have a way to check it now, even though that wouldnt have a bearing on the firmware issues.

I went back unthread and re-looked at your configuration.h file and realized its different than mine. I am using marlin 1.0.0 beta 1 where you have RC1. Try this. Change the version string to today's date andouille in your name for username at the top of the file, and then set your E to 650. Recompile and re-upload to the Arduino again. After it uploads, go pack into Pronterface and connect to the printer. Does your name and today's date show up in the dialog window? If not, unplug power and the USB from the Arduino and reapply them, then reconnect via Pronterface. If you still don't see your name, then we will know it's in the upload that things are failing.

Hmm, wish it wasn't connecting :/ That would be easier to solve.

Do you think changing to a beta of Marlin would be the ticket?

Changing the firmware settings continues to have little effect on extruder, still changes the other axis's though, no idea...
New symptom that might be related. If I tell pronterface to extrude 30mm at 15mm/min it will extrude for exactly 1 minute then stop, its supposed to extrude for 2 minutes. It also extrudes about 18-22mm worth of input lol. Somethings fishy there and im pretty sure its related to my original problem.
But, ive got an update of a video and some photos.
Heres my short video taken just now: [youtu.be]
Ive uploaded some photos, the best print so far is the stone village house that took about 5 hours to print. After that, the kapton tape has been oozing ever since, creating black streaks and chunks in the prints. Ive since removed the insulating blanket to make the problem less severe. I must have gotten a cheap batch of kapton from amazon because its definately not supposed to melt at these temps.

Sounds to me that your hotend can not keep up with the speed you are trying to extrude and then the pinch wheel (hobbed bolt) slips. The reason I say this is because you probably have 18-22mm's of molten filament when you start to extrude and it all comes out. Then the filament slips when the unmelted filament reaches the tip.
What type of hotend do you have?
PLA or ABS?
What temperature?
What type of extruder?
Do you have springs on the Idler?
Do you have the Idler applying a lot of pressure on the filament?

Just watched the video and I see you are using PLA and the hotend is either a makergear or homemade. I also notice it is really long and most likely the hot zone is too long. I would add a fan blowing across the upper part of the hotend. You should be able to touch the coldzone of the hotend without being burnt. You want it to be below 60c at the top and it should only go above 60c in the last 10-20mm before the heater.
