I would guess that the pins are not mapped correctly because the sanguino wiring i/o may not be correct. read the instructions, and see if this all helps.
what tests have you done to test the end stops? are you sure the pinouts are the same as before for the i/o?
list all of your code by uploading a zip file. someone here will likely help you out!

thanks, and also thank you for posting your solution. please note that the arduino as a isp seems to have errors in programming boot loaders for larger than 64k devices, such as the atmega 2560, or the ATMEGA 1281 replacement alternative to the 644p with more memory. this is why it is a good investment for an avr programmer.
here is a link i found to help program the 644p.

Is there any way you can do a high resolution image of the bubbles you see? I'm trying to analyze what they are and would like to see details down to the line height. please can you upload another image? thanks!

read the reprap wiki. many things you ask are answered there in great detail.
printers that are recommend are listed on the site as well. for new users that want to learn about printers i would recommend a prusa. if your not into printers but want one that works there are several options available. your due diligence and research should help your decision.

it is likely they work fine. you will want to look for fans that have a high CFM (cubic feet per minute) air flow. my guess is the average is about Air Flow: 6.7 CFM, also use the term "HIGH-VELOCITY'
something like this may work,
it has 19.7 CFM,
as a side note, I find that cooling with a duct that surrounds the extruder provides the best results, because the reason for the need for the h

g29 uses probe data, and recalculates z height, g28 homes and resets all values. for probing to work correctly use g29. offsets for z height when probe retracted should be calculated by settings in firmware.
the settings in firmware may be what you need to change
there is no need for g28, after g29
do you only have a probe for z, or do you have a limit switch for z as well. normally home z to

file tab, select machine settings.
then maximum width=300mm (diameter)
then maximum depth=300mm (diameter)
height= 398.99 in my case, yours will vary.
with centering of objects, it will try to do that when it loads. if there are any artifacts that extend beyond your part, they will be captured as triangulation data, and still be part of the centering algorithum. remove the artifacts. look for a

would this help?
here is also gcode that runs circles on printer. you need to load the stl file and generate gcode.
there is however gcode created for both delta and Cartesian machines.
load the delta gcode.
it still needs a few people to test it.
it still has extruder going during process, so if feedstock is loaded it needs to be up to temp already.

one way to find out. especially because the sd card is near the motor and next to vibrations, and emf noise. un- mount the board, move its location 6 inches away and see if the issue still happens. it looks like your connector has a lot of extra wire on it. i would trim that down. extra capacitance of longer wires and rf energy on wires that go no where can not be ideal.

are you using pla or abs?
I would think you are printing too fast. looking at the videos on this printer, it looks like it is an entry level printer, you will need a fan cooling the hot end down for use with pla, and tighten the grip on the feed stock going into the cold region of hot end.
let me explain, by not cooling the hot end in the cool region, heat creeps up, and causes a large area of

do you want the pi to use its i/o to turn on and off supply as needed, or to send a code to reprap controller and have it turn on and off atx supply. also where is the menzi board receiving power from?
depending on approach, you could use one of menzi's available port pins, such as in the header, or use wiringPi language and a port pin on the Pi. I'm not that familiar with Pi modules.

you will want a replacement heater cartridge. don't mess with the old cartridge that is damaged. since your not an expert in this kind of setup, i would not repair it. it could void your warranty and possibly damage other components, overheat, or cause fire.
you can order them online if the vendor does not replace it for you.

I think you need to talk to a lawyer about these things, any advice given here would be trivial, and should not be taken as advice for what you are trying to accomplish.
Also this site is about open development, and GNU licensing.

what is the gage of wire use to connect power to your bed. is there any way you can use two or 4 wires? do the wires get warm?
how about power to the mosfets, do you have more than 1 gnd and positive wire to the leads from the supply. it could be your current is limited by the wiring
do you have the bed with glass on top, and insulated on the bottom side?

can you post your gcode. this will help. by post it i mean upload the gcode file. it will help diagnose why z is raising. it more than likely is that no gcode is processed such as when a parser error happens, and that just the beginning code and end code are run. this would mean heat up and run, and then z lift and end.

may have been mentioned: sd cards can be come corrupted easily. especially when cached on a pc.
have you tried reformatting sd card , and then placing files on card. renaming files, or copying over files on sd card messes with the sd card file read, the firmware becomes confused with finding file data when it is not all together, such is the case in rewrites, or when sd card is not ejected befor

extruder motor usually does not move unless nozzle temp is sensed above 150deg c. I would try to heat up nozzle to at least 170 (when pla flows easily) then fwd extrusion until feedstock flows thru to the nozzle and exits as filament.
check your z height. did you start print with homing z? and did you do a G28 or include this in your gcode?

download arduino ide, then download ramps marlin
there are instructions available here: look in Compiling new Firmware section
from the tutorial page it states
Once you have all the circuits setup to use the pins you can simply define them in the Gen 6 part of pins.h. For Marlin I made the following modifications, my pins.h is also shown below.

I am assuming you switched from 3mm feedstock to 1.75mm feedstock?
can you show a picture of your machine? it may be in your case the extra force required to pull the feed stock could be slightly lifting the z axis. in this case a piece of tubing about 1 foot long inserted between the extruder and the feedstock would help. since no heat is applied to this section, and only concern is friction,

this is likely to lead you in the right direction. you want to search for things that do gerber files

in reality you will need spring tension as filament shape may stress to a different shape such as oval, and it can happen even during load and retraction. you may be better off with a knurled tool end, but I'm not sure entirely on how you would be applying pressure to it. the belt extruder idea. what benefits does it have with it other that less backlash?

i would guess it is better to try it out, see if it works for you, and if you have good success let us all know. we only get things better if we try and then share them!
as posted there are concerns about how much temp they handle and repeatability, but these are things that could be resolved easily.

keep in mind voltage can spike about 4 to 6 volts above rail voltage. make sure noise on rails is suppressed. also take into account that running a chip at max voltage any load spike can damage driver chip. the best way to avoid over voltage is a diode clamp setup, but this means overshoot is at least 0.6-0.7v. and diode response needs to be fast!

what are you trying to print, can you include gcode file as well as the firmware you are using, and possibly the stl file? also what slicer used.
also what happens if you print from a computer, do you have an error log?
and do this first, format the sd card, then place the file on it. try it again, does the print finish?
it can be a file card format issue, sdcard damage, firmware issue such as
