Re: Wow, firmware help!(RAMPS) - 15 years ago

also, fixed the Z axis issue, for whatever reason the firmware had the steps per mm 3200/1.25 (or something) changed it to 87.25 or whatever (same as x and y)...i think i might be ready to print?

Re: Wow, firmware help!(RAMPS) - 15 years ago

im assuming it is a replicateorg issue beacuse whne i try to send the feed command it does not show the e extruder having a change in value like it does with x,y, and z. i would test in repsnapper but i dont have the program

Re: Wow, firmware help!(RAMPS) - 15 years ago

E0 (what im plugged to) is the default for the extruder. still nothing...i tried a different stepper carrier, and nothing... the define is changed to RAMPS 1.3..what am i missing?

Re: Wow, firmware help!(RAMPS) - 15 years ago

heater works, and inverting the endstops made it so i can go forward and backwards, but the axis' tend to mess up (i press jog x and it moves x and y, but not everytime, and z always goes 100mm no matter what)! as for the high-rpm value... how high? i entered two in the 100-200 range and nothing

Re: Wow, firmware help!(RAMPS) - 15 years ago

thanks for all the help! i have sprinter running on my ramps setup currently, and can control the x y and z axis in a positive direction, but not reverse? also, the extruder wont work....hmmm how do you test your heater through replicatorg?

Re: Wow, firmware help!(RAMPS) - 15 years ago

Alright, i tried changing teacup to support ramps 1.3, but half the pin definitions dont exist and i dont know enough C to fix the massive amount of errors i create by changing the pin definitions. theoretically, can i just load sprinter and be good to go with replicator G?

Re: Wow, firmware help!(RAMPS) - 15 years ago

On the teacup wiki page it specifically says it supports RAMPS boards?

Wow, firmware help!(RAMPS) - 15 years ago

Hey guys, i just set up my whole bot, now im trying to actually get it moving. i want to use either the replicateorg software (with teacup firmware) or the reprap.org fived_gcode setup. i can get the replicateorg software rujnning but when i try to jog the axis it will only let me jog the x axis, and when i press "x-axis" it will jog the E0 stepper driver carrier on my board! i think this is a so

Does anyone use more than 12v for hotend?(prusa) - 15 years ago

Hey guys, im almost done with my prusa. only thing left is to buy 4 stepper motor drivers from pololu and plug them in the ramps, and figure out/ attach a hotend to a wades extruder. does anyone have a picture of a hotend mounted on a wades? i can find a pictures of hotends mounted on other extruders but not wades. also, does anyone use 24v for a hotend design? i have one design that uses 12v an

Re: NiChrome input voltage/ amperage (Prusa) - 15 years ago

ugh im confused. so if i need a specific resistor it seems im better of trying to get the nichrome to work unless i can get the resistor and thermoresistor from the same supplier

Re: NiChrome input voltage/ amperage (Prusa) - 15 years ago

Thanks guys, i was wondering if a standard resistor (radioshack version) was the same as what i need at it appears it is. on a side note, will ANY 100k thermistor work?

Re: NiChrome input voltage/ amperage (Prusa) - 15 years ago

i ordered some insulated NiCr from makergear and it should be here soon. where can i get that resistor? is it a better bet?

NiChrome input voltage/ amperage (Prusa) - 15 years ago

Hey guys, was wondering if anyone knew offhand the voltage and amperage inputted into the 6 Ohm length of NiChrome? I need to mock up my hot end to see if it actually works without buying a RAMPS setup... Thanks!

Arduino mega vs Uno vs Duemilanove - 15 years ago

Are these interchangable with the standard RAMPS package? I'm new to reprap's and am currently building a prusa, having a hard time finding the Arduino MEGA board, thanks!

Re: New Reprapper (electronics question) - 15 years ago

i guess ill go with RAMPS then guys, Thanks! Now one question...where can i buy the parts?!

New Reprapper (electronics question) - 15 years ago

Hey guys, i just decided to build the Prusa version of the reprap and the mechanical side is going well, however, i was wondering what electronics to choose from. I read the wiki page on electronics, but it did not specify price/ ease of use/ availability on the electronics. As far as i know, RAMPS, Gen 3, or Gen 6 seem to be the best choice for me. I am capable of circuit board work but have nev
