A picture would make it clearer what you mean, and therefor more likely to give the the correct answerby lazzymonk - Printing
Re: Print bed will never go over 85-90C - 12 years ago
I think it is between 1.0 and 1.2 ohm. im sure someone will correct me if im wrong. if it is too high you cant get enough current through it to heat up enough.by lazzymonk - RAMPS Electronics
Re: Print bed will never go over 85-90C - 12 years ago
have you checked the resistance of the heat bed?by lazzymonk - RAMPS Electronics

Have you tested a different motor on a different driver?by lazzymonk - RAMPS Electronics

What voltage power supply do you have attached?by lazzymonk - RAMPS Electronics
Re: reprappro mendel help please - 13 years ago
Some firmware won't run the extruder if the hotend is cold to prevent damage. As for why it won't connect now? Could be many things. Have you restarted your computer? Tried a different USB port? Mine reinstalls drivers and creates a different com port if plugged into a different USB port.by lazzymonk - General Mendel Topics
Re: Newbie need some help... - 13 years ago
Have you got the end stop plugged into the correct socket. If you have the min plugged into the max it won't stopby lazzymonk - General Mendel Topics
Re: Newbie need some help... - 13 years ago
#define INVERT_X_DIR false // for Mendel set to false, for Orca set to true #define INVERT_Y_DIR true // for Mendel set to true, for Orca set to false #define INVERT_Z_DIR false // for Mendel set to false, for Orca set to true around about lin 235 in configuration.h of the firmware. give it a lookby lazzymonk - General Mendel Topics

Mount attachedby lazzymonk - General Mendel Topics
Re: Marlin/ LCD-Keypad Code Mod - 13 years ago
I totally agree, im a programmer by trade and marlin seems like a jumble even to me. Is there a simpler more customisable firmware that anyone can recommend? stupid spam filter on this forum is kicking up a stink lolby lazzymonk - Firmware - mainstream and related support
Re: calibration.... - 13 years ago
you need to calculate and set the steps per mm in the firmwareby lazzymonk - General
Re: No enough room below x-carriage for 40-mm fan? - 13 years ago
The blue mount holding the fan onto the red carriage? That is a 40mm to 40mm mount. I designed the carriage to take a 40mm fan there but rather than making the mount part of the carriage i wanted separate so i could attach other things there instead, like my dial meter or a pen for plotting. i can share the designs for sure. you after the carriage or the mount?by lazzymonk - General Mendel Topics

Re: Uploading bootloader to ATmega1284P in Gen7 1.4.1 board - 13 years ago
are you sure it is a ATmega1284P chip?by lazzymonk - Controllers
Re: No enough room below x-carriage for 40-mm fan? - 13 years ago
I have attached some images of a carriage I designed to take 2 30mm fans for cooling my jhead which are always on and one 40mm controlled by ramps for cooling the print. The red one is the second version with the 40mm mount. Blue is the prototype without it.by lazzymonk - General Mendel Topics
Re: Upload error, stk500_getsync(): not in sync: resp=0xee - 13 years ago
I use great kit works great. Uploads work every time, they do other kits too if you don't need everything in that oneby lazzymonk - Controllers
Re: Have you tried a "fuser." - 13 years ago
They still are in some cases. We have 6 month old, a very large (6 meter long) production color laser printer at work and the fuser is heated by 6 35cm long halogen lamps.by lazzymonk - General
Re: Upload error, stk500_getsync(): not in sync: resp=0xee - 13 years ago
Silly question, but are you sure the atmega is running? If so, there are 2 more thing you can try. Go through the instructions again ensuring you follow them to the letter. Or unplug everything, even the drivers just leave the USB and try again. Which you do first is up to you.by lazzymonk - Controllers
Re: Upload error, stk500_getsync(): not in sync: resp=0xee - 13 years ago
i know that problem happens with standard arduinos when something is stopping the auto restart. Try uploading the firmware and when it finishes compiling and starts uploading hit the reset button.by lazzymonk - Controllers
Re: programing your second hotend as a heatbed - 13 years ago
The way i would do it is. make a small pcb with 2 mosfets connected to an single aux pwm pin, supplied with 12v directly from the psu. then just change the pin in firmware for the bed.by lazzymonk - RAMPS Electronics
Re: Looking to buy a prusa Mendel kit in the UK - 13 years ago
There have been some negative reviews of www.nextdayreprap.co.uk lately. Things like not replying to emails.by lazzymonk - General
Re: programing your second hotend as a heatbed - 13 years ago
im sure there is a good reason why you want to do this. I cant help with that, but I cant help but ask Why would you want to?by lazzymonk - RAMPS Electronics
Re: Reprapworld PLA Filament - 13 years ago
I have some pla that works fine at 185, I have others that need over 200 and one that needs 215 also. I have the temp of my hotend calibrated by a highly accurate temperature probe. If your temp is off by a few % you might need to go higher than 215. Just keep increasing the temp until it prints ok.by lazzymonk - General
Re: Issues uploading sprinter to Sanguinololu 1.3a - 13 years ago
Also check that you have the correct device selected in the arduino software. Basically ensure you have done everything in the readmeby lazzymonk - Firmware - mainstream and related support
Re: Issues uploading sprinter to Sanguinololu 1.3a - 13 years ago
Try downloading and or extracting the firmware again. There may be a file missingby lazzymonk - Firmware - mainstream and related support
Re: Reprapworld PLA Filament - 13 years ago
What temperature are you trying to print it at?by lazzymonk - General
Re: Issues uploading sprinter to Sanguinololu 1.3a - 13 years ago
It's the firmware that defines which version of the arduino software to use. Not the board. It would try 0.23 as instructed in the sprinter instructions.by lazzymonk - Firmware - mainstream and related support
