newbie to this 3D printing ive bought one of the Pursa i3 clones here
got it for £100 ive done a few upgrades one being changing the Zaxis 8mm threaded rods to these
ive been on the prusa calculator for changing the steps 1600 it came up with put that in but the prints still coming out very wrong Height wise,seem the nozzle is lifting to high for each layer.
tried a trial piece that should of only been 30mm came out a mess mass of filament but at 6inchs high lol
i have the Neema 17 steppers 17HDC4023-24B
where and wot do i change on the lcd to put this right?
im also thinking of putting marlin on it is there much to do or anything specific i need its 2560 Rev A board white not checked the chip yet
hmm so any idea where i put this info i did flick through the LCD and find zstep/mm it had 2560 something for the 8mm threaded rods. is this where i put the 400,
the other problem is where i changed the Zsteps/mm from the 2560 to wot i thought was right (1600) it reverts back to the 2560 again.
is there something im missing!!
yes your missing a pc, running some sort of control program (eg pronterface)
you either update the setting in firmware and then upload the new firmware (which you probably dont have as most supplier dont give it to you, even though they have to its part of the T&C for using the firmware...)
Or you connect a pc to the controller and send the commands
"M92 Z400" set set the Z steps/mm
"M500" store the value in eeprom. If you eeprom enabled.
But this can vary, depending on what firmware you using.
There is also a 3rd option, you just add "M92 Z400" to your gcode start file in your sliceing program, but this is a nasty kludge and not recommended
Looks like it might be a makerbot clone running sailfish firmware... so all bets are off (alll things makerbot is the devil from reprap point of view)

Repetier host has a built in eeprom editor, you can change the Zsteps/mm and Z max feedrate via that editor
yeah been having a play about today as ive been off work found out there was aeeprom editor after reading through the forum for over an hr lol
trouble is it reverts back everytime the machine is switched off .is there a way to write this to the eeprom ive saved my original settings.
ive also done a few test pieces and had a vast improvement on my prints seems to have gotten rid of the Z ribbing ..
next upgrade im hoping is autobed leveling is it possible with what ive got
