1. Backup the file pronterface.py 2. Open it in text editor and find statuschecker method. 3. replace "string +=" with "some_descriptive_variable_name =", so "string += _(" Z: %0.2f mm") % self.curlayer" will become "zHeight = _(" Z: %0.2f mm") % self.curlayer" 4. add list of added variables below string = "" line like: string = "" zHeight = "" 5. add string = zHeight + your_variable1 + your_vaby miso - General

According wiki page there are two versions of melzi board. One with and one without ftdi chip. Which one is yours? Do you have PWR jumper installed? Have you also tryed different USB cable?by miso - General
According to that error it looks like problem with serial port. COM3 either doesn't exist or user running pronterface doesn't have permission to access it. Is ftdi driver properly installed? Does FT232 show up in device manager when you plug in the board? Some info on driver installation is here. Or does this problem occur only with pronterface and other software communicates well with your boarby miso - General

Slippage is definitely not part of the game, and filament shouldn't slip. Maybe extruder is driven too fast, either because of incorrectly set STEPS_PER_MM, or using absolute units in slicer and relative in firmware. Or there's to much friction in hotend, temperature too low or problem with filament drive (hobbed bolt, springs, etc).by miso - General
There's usually only one transformer with both 12V and 5V coils wound on the same core, so increasing output voltage to compensate for voltage drop on loaded 12V will cause overshooting on unloaded 5V rail.by miso - General

Hi, when I try to slice attached object, tube with window cut into its side wall, I get support material on layers 25+ that is not fully supported by support generated on lower layers. Skeinforge used is sf-50 from repository. Is there anything wrong with my design and/or way to fix this? Thanks.by miso - Skeinforge

Mistyping temperature is real danger and definitely can happen. So I have hard-coded check for 250C to temp_set() in temp.c forby miso - Firmware - mainstream and related support
Hi, given the fact that excessive temperature can damage some hotends (PEEK softens at ~250 C), it could be useful to have temperature limit set in firmware to act as safety measure. I dont know about other firmwares but Teacup seems to lack this feature. Was this ever considered?by miso - Firmware - mainstream and related support

I would like to install Mk2 PCB heatbed on my printer in similiar fashion as described here , but my top plate is made of acrylic, not wood. Is it safe to use heatbed on acrylic, or should I replace it with wood? What (minimum) amount of standoff should I use? Thanks.by miso - General
Till someone came with such mechanism we can only speculate. But I expect it to be complex, error prone and innacurate. Motors arent that expensive, prusa is using two stepper motors on Z axis instead of one used on original mendel because its cheaper than belt drive.by miso - General
Thats bacause they are XL not T5, you will need XL belt. They also have 6mm bore while most steppers for reprap have 5mm shafts.by miso - General

No, wire is not insulated. I plan to insulate it using PTFE tape as described here.by miso - General
jcabrer: Unfortunatelly I don`t have suitable appliance at hand to source nichrome wire. I have finally bought isotan wire with 10Ohm/m, as far as I remember lenght of 30cm was recomended, so 20Ohm/m would be more suitable, but was out of stock. My biggest concern is how long will isotan wire last operation at required temperatures, but I will try and post results. EDIT: posted incomplete messby miso - General
Thanks for suggestions. Meanwhile I have found claims that PTFE threading will fail sooner (printing ABS) or later (PLA), so I am thinking about putting nut and washer on heated barrel just under PTFE rod, and use it to support axial forces via some horizontal bar there. Then I should be able to use something as simple as couple of layers of tape up on PTFE rod to keep filament holes in extruderby miso - General
Hi, I am looking for a way how to mount my afghan lathe style hotend to Wade's geared extruder. I have used 10 mm PTFE rod, while hole in extruder body is made for 16 mm. Does anybody have proven solution for this problem? Thanks.by miso - General
Hi, can be nichrome substituted by kanthal, isotan (ferrous based) or constantan (copper based alloy)? All have melting point over 1200C, isotan claims good chemical and corrosive resistance. Which would be most suitable? Thanks.by miso - General
