Fuses would generally stop all motors from working.... You have probably damaged the stepper drivers Luckily your board is modular, they can be replaced. First check this is the case While everything is off, swop the driver from X and Y positions, re test, does X stop working and Y start working? if so You have identified one dead driver.. repeat with Z drivers If the fault doesn’t move youby Dust - Controllers
Agreed... You can run without endstop, and set you position manual with g92 command But its a pain in the butt!!! you have to set this manually every time your turn on the printer as it thinks it as 0 when powered on, till its told otherwise via homeing switches. (X and Y aren’t so bad, it Z that’s the issue) And yes it sounds like your power supply is crap, get a better one.by Dust - General
Sadly people get taken in by fancy LED's and buy switch based endstops with leds, these use all 3 pins. Signal, Ground (marked as -ve) and +5v If you plug them in the correct way around, they work fine. If you plug them in backwards, you short +5v to ground via the closed switch and smoke the voltage regulator. Sadly there is no key on this connector... so people plug them in any way they want.by Dust - General
drv8825 have different micostepping, you should set it to 1/16th micro stepping using the following table Jumper off is LOW, Jumper on is HIGH For vref seeby Dust - Stepper Motors, Servo Motors, DC Motors
no, I’ve never seen that board before. They have changed it without document it Where did you get this board? got a url? maybe there is some documentation there.by Dust - Sanguino(lolu)

The dimensions will always be out... as the paths have allowed for the thickness of the extrusionby Dust - General
normally it would be like If your lucky they have just move the 4 pins over so the last 6 pins are what you need.. Your going to have to trace the board or find the manufacturers documentation I think what they have done is added the glcd converter on boardby Dust - Sanguino(lolu)
It should be about 1.1 ohm for a standard PCB heated bedby Dust - Prusa i3 and variants
Its different depends on what programmer you have, and what chip you have (644p or 1284p) but take a look at my old notes and some 1284p notes and Finally best way to add Sl support into the current arduino IDEby Dust - Sanguino(lolu)
Steppers voltages are somewhat miss leading, you need 3 or more times the rated voltage to drive them So you need a 36 volt system.... You would need completely different external stepper drivers, something like drivers + a 36v power supply... These steppers sound like they are more aimed at CNC machinesby Dust - Prusa i3 and variants
Apparently that socket is not rated for 15amp.. several have reported that the fuse was fine, but the holder caught on fire!by Dust - Reprappers
Hi Guys, Its been a few weeks, No one seems to have objected to the idea Can we proceed? Thanksby Dust - Administration, Announcements, Policy
What coil sequences are you doing... Thats a really odd angle... its not even a multiple of 1.8 What the stepper part number? Your sure its a 4 wire Unipolar ? It would be a strange beast... most are 5 or more.by Dust - Stepper Motors, Servo Motors, DC Motors
Attempted to ask geeetech live chat support... man that was a waste of time!! It looks like its a 603 15 amp smd fuse... but details like a useful part number so far elude me... hopefully others will have better luckby Dust - General
looks to be a gt2560 board... Not sure on the fuse yet,,,by Dust - General
Microstepping is more about smooth travel... you want 1/16 on X,Y and E, most run it on Z as well, but some prefer 1/8th Yes you then just adjust the steps/mm settings to in firmware to match what you have set in hardware Speed is not related to this* (*it can limit your max speed, but not till your going over 150-200mm/s! ball park figure) Speed is determined by the feed rate you request tby Dust - General
The red, yellow and blue rectangles are the micro stepping Jumpers There are 3 under each pololu module Here is what they look like without jumpers Here is the table For pololu modules, when the jumper is off its LOW, when a jumper is on its HIGH Here are some different jumpers, they are just a plastic shell over a peice of metal, used to short two pins outby Dust - General
Found after 30 seconds of googling...by Dust - RAMPS Electronics
Some controller boards are hardwired to 1/16th micro stepping (pcb track under the jumpers) But a lot are just jumper pins that need closed with jumpers under where the pololu modules sitby Dust - General
Some cheap megas from china have a different usb chip See if yours has a ch340, if so you need ch340 driversby Dust - General
To check for a bad regulator... Plug in just the mega via a usb cable to your computer, upload blink as a test sketch it should work like normal With sketch uploaded unplug the mega and power it from the dc jack (this also goes threw the voltage regulator) Does the led still blink? If the regulator isnt working at all, it wont run blink. You should also check 5v pins for 5 volts with a multimetby Dust - CoreXY Machines
Its probably a dead stepper driver... but if they are swappable on your controller, I have no idea... no idea what controller they use these-days also check the stepper wiring... I’ve read somewhere that these machines have a different stepper on the extruder, and the wring is different to the X, Y and Zby Dust - Reprappers
That is a 5v regulator, its quite replaceable (its a NCP1117ST50T3G) It blows most commonly when you have a short from 5v to gnd (but anything that sucks to much current from the weak 5v line will do it) The most common cause for this on 'normal' machines is switch endstops that are wired backwards so the switch shorts +5v to gnd instead of S and GND You can find them on ebayby Dust - CoreXY Machines
does it buzz?? If so feed rates might be to high do a M503 (Print settings) and look at the setting for M203 (max feed rate)by Dust - Reprappers
