So if I use a Wades Extruder which uses the vanilla mounting holes, I can just bolt it on your design, right? I was not aware that other extruder designs used custom mounting solutions...by Cyberwizzard - General Mendel Topics
I need to adjust it a little to hold my new light bars but it seems there are plenty mounting holes. Last question then: why do I see people adding wooden mounting plates to the carriage? Is that for heat issues or for structural reasons?by Cyberwizzard - General Mendel Topics
I found your design before posting all of this so I had the feeling that it might come up I like the idea of a lighter carriage with more room for my fingers when I need to fiddle with stuff. Does it hold up above a heated bed as well (and does it need to made from ABS in order to do that)? Since the image host on Thingiverse seems to be on holiday break as well: how does your design attach thby Cyberwizzard - General Mendel Topics
Cheers for the input. Is there a design for such a carriage? I only found a conversion plate that bolts onto the top of the original carriage design.by Cyberwizzard - General Mendel Topics
The downside of the newer extruder designs is that the engine block is hanging out due to the gears. I have a Wade extruder design in my Mendel and together with the rather big stepper motor, the whole thing is hanging out. I 'solved' this by restricting the accessible build area to make sure the carriage will not bump into the electronics or the A-frame. But since I need to replace the vertexby Cyberwizzard - General Mendel Topics
I've left the flow rate at 16mm/s as the default in Skeinforge and I figured out what went wrong. When setting up the volumetric printing, there is a setting in "Speed" => "Flow Rate Setting" which was set to 210, as the wiki explained how it related to DC extruders. What it didn't mention was that this setting is far from obsolete: it should be set to the same value as "Feed Rate (mm/s)" asby Cyberwizzard - Reprappers
Cheers for the suggestion but I managed to spot that one during testing without plastic: my extruder would move a bit and then churn air for long periods of time which appeared to become worse during the build. I then found out that my Teacup firmware was expecting relative values so every move the gap for the extruder became worse. So its not that; but it does leave me with the feeling that I hby Cyberwizzard - Reprappers
Thanks for helping me out. Is your 40mm/s at the ingoing side (so raw feedstock) or 40mm/s on the outgoing side? And just to be clear: is that what Skeinforge thinks its feeding or what you actually measured while calibrating?by Cyberwizzard - Reprappers
Update from a full days of printing trash material... I started out with a calibrated extruder: if I ask the extruder to feed 10 mm of feedstock, it would feed exactly that. After a while I concluded that part of my problems are due to the speed of the extruder: feeding slowly is not an issue but the RepRap Host Software and Skeinforge (rev 44) code sent it spinning. Observing one of the runs,by Cyberwizzard - Reprappers
Ahh, so I am in the range of what can be considered normal then. Edit: I just saw that you mentioned 40mm/s instead of 40mm/min. Perhaps I should increase the base temperature to be able to push plastic down faster... I am also puzzled about the E_STEPS_PER_MM setting. I gathered it should be the number of steps to pull one mm of feedstock into the machine. I calculated this, verified it when Iby Cyberwizzard - Reprappers
I've begun to break in my first Mendel and I got it to print - sort of.... I've got a Wade extruder (the one with the 39/11 down-gearing) and I think the hobbed bolt I got is not really good at gripping the PLA I've been trying to feed it. Regularly, I can see the gears move but the PLA holds still. The default setting in the RepRap Host Software is 3000 mm/min for the extruder. While it can doby Cyberwizzard - Reprappers

Ik probeer uit te vinden waar ik PLA op zou moeten printen als het niet direct op MDF kan. Ik lees dat glas zou werken, mits verwarmd. Dat valt dus af omdat ik nog geen heated bed heb. Verder heeft iedereen het steeds over Blue Tape wat een schilderstape zou zijn. Ik ken het spul niet en mijn schilderstape is meer papier dan plastic. Het alternatief daar op is Kapton Tape en wederom is dat ietby Cyberwizzard - Dutch User Group - Archive

Can some one help me please? I am trying to figure out how to connect the thermistor to the Gen7. Looking at the 1.3 schematics it seems that only a +5V and Arduino sensor input are used. Since I have a 1.2 board, I reckoned I should connect the thermistor to the +5V and the sensor pin (top pin and middle pin on the Gen7 1.2 PC.

I'll post it later as I use a VM to program the Atmel on my Gen7. On a side note, I am describing the same problem as the topic starter so it is not a configuration issue... And while the discussion sort of side tracked, I do not think a solution was given except for a remark that it 'should' be fixed in git somewhere.by Cyberwizzard - Firmware - experimental, borrowed, and future
It is not the maximum Z position that is exceeded but the maximum Z speed. For example: when I specify MAXIMUM_FEEDRATE_Z to be 100, the homing command uses this as its speed. When I send G codes and I specify a speed of 200, the firmware will attempt to actually move at 200 mm/min. Since G01 movement commands accellerate (and the homing does not), my Mendel will actually move at speed 200. Hoby Cyberwizzard - Firmware - experimental, borrowed, and future
While testing the 3 axis of my newly build Mendel by manually sending G-codes, I found out that my Z-axis locked up every now and then. After a bit of testing it looks like the same issue described here: the driver attempts to drive the stepper motor beyond what it can actually push or pull and it just stops and hums angry at me. I've searched the Teacup firmware to find some sort of limiter toby Cyberwizzard - Firmware - experimental, borrowed, and future
