Re: Extruder Stepper In and Out - 15 years ago
jcabrer: You seem to have found a solution for a problem thats different then waht you describe. You fix the Homing of E by homing all three axis?? The homing of E is done after the retract so we dont have to deal with 1000s of mm's. Nothing else... So it is needed... And when you moved to SF40/41 have you changed your E-steps in the Firmware? Thank you for the update btw.by ahmetcemturan - Skeinforge

@jcabrer: Can you post an update so People who have similar problems can find a solution. Thanksby ahmetcemturan - Skeinforge
Re: Idea for Cool - 15 years ago
You can add a code to the beginning of the cool and to the end by adding a gcode file to the alterations folder.. So it can go there wait the time then go back. I never needed that but I think you can make it work. I think your real problem is your Extruder heater control...by ahmetcemturan - Skeinforge

Re: Extruder Stepper In and Out - 15 years ago
From what you tell it looks like the Retraction is working but your actual filament extrusion is not happening... It could be that You have some Gigantic settings for the filament diameter (2.8) or the packing density ratio (try with 1) !!Note that the decimal has to be POINT not comma!!by ahmetcemturan - Skeinforge

@NelsonRap: What you do is not wrong. I just think that you dont get really that much speed on the extruder stepepr with Gen6. Try lower settings and look whether you see any diffference in the retraction speed. You will probably not see any. It also does no harm when you leave it @50. I would advise you to switch to the Sprinter FW anyway as it is much better and faster. You can pull itby ahmetcemturan - Skeinforge

Re: Start code & end code - 15 years ago
Hi NelsonRap, dangereous Endcode IMHO.. G91 G1 F70 G1 Z7 F70 G1 F2300 G1 X-100 F2300 G90 M104 S0 How can you be sure that You can go down to 7mm with your Z.... You might crash your extruder and x axis into the print... I would remove the Z code and let the head move to some Parkposition only and turn off heater...

Basically Gen6 with original firmware somehow has a limit on how fast the extruder stepper can run... Not the case with sprinter FW..by ahmetcemturan - Skeinforge

Wow thats big... Btw: > a negative number. This means less filament is fed can cause you lack of PLA if you have a small part that has lots of retracts after short moves. It looks that you have a really slow extruder retraction speed. Basically you have to retract faster than the filament oozes and get put it back before it starts oozing again. That means : You must retract filament as quby ahmetcemturan - Skeinforge

Is your extruder barell, square to your printbed (90odeg)?by ahmetcemturan - Skeinforge
Re: Mendel and Skeinforge problems - 15 years ago
Hi, Here are mine, but slow down feed and extrusionrate under speed, as you wont probably be able to reach them. (I use klimentkip fw) The file is settings are for ,33 layer thickness PLA.by ahmetcemturan - Skeinforge
Proposed enhancements for Skeinforge - 15 years ago
Dear fellow forum members, I would like to bring up a few ideas that I have for SF. Unfortunately I am not a programmer and can not do these alterations myself. (Maybe someone shows me the way). I would appreciate if I could get help.. (I sent this to enrique already but didint get any response, so I am trying my luck here..)

Let me guess: It happens when the Y stepper pulls the platform to itself...(Or when the X stepper pulls the extruder to itself if you have the new x motor mount with the belt teeth inside).. if so it is because of the belt tryingto hop over the berings... It only happens on one side beacuse you have more tension on the belt when pulling..When "pushing" there is less tension. (of course there isby ahmetcemturan - Skeinforge

Re: Skeinforge 40 Changes to Dimension - Read this for problems with the new version of Skeinforge! - 15 years ago
Hi brnrd, My point is that we can actually only measure the input correctly. What comes out, the software has to calculate. So when I have calibrated my extruder to input 100mm when I tell it to input 100mm then I dont need to correct how far the teeth dig into the filament (as long as the consistency/hardness of the filament does not change..) So that factor should remain 1 if you calibrate byby ahmetcemturan - Skeinforge

Have thickness and altitude in Bottom 0. In Raft make all Thickness ratios 0 except for Operting Nozzle Lift over Layer Thickness... Make it 1. Your first layer should be at your layer thickness height now.by ahmetcemturan - Skeinforge

Hi Nophead, I adore your work, research and blog btw. Have a look at these links please.. So the Density changes about 10% but if the the die swell is also about 10% I think they cancel each other out. So you get the same result in the end. If someone uses another hotend with a big or very low swell then the calulation will be off. I think that You need to calculate the correct volumby ahmetcemturan - Skeinforge

Hi, First of all let me say that I am not a programmer but I looked into the code of the Dimension.py file. What I understand from it is that the FPDR is just used as a direct multiplier for the crosssectional area of the filament diameter. So it is not a multiplier for the feed as we have assumed. It is intended to be a correction factor for density change and die-swell and shrinkage. I am cuby ahmetcemturan - Skeinforge
