Rescaling multi objects at once - 7 years ago

So I had a prusa knock off an it just has issues.. so for giggles I got a M3d micro just to play with.. and the kids to play with.. it works.. its slow.. and has small bed.. so trying to print some toy gun for them.. too bad its not going to fit a full size.. so is there any program that you can give it multi objects and it can see which needs to be scaled down the most and applies scale and the

Stepper Motor Clicking fun - 8 years ago

so I had the board go and replaced it.. and now I cant get the old extruder or new to work. I was always assuming it was the voltage. I had it at .9 and all the way up to 1.1 and still click click click.. I dont wantto crank it up too much since I hear it will over heat. everything I read people had it at around 1.1 or lower.. should I just keep going higher ? or could it be some other issue..

Y home is off bed - 9 years ago

board I used to have was over the 200x200.. it was not heating correct.. so had to replace with standard 200x200 but now when I it Y home it goes off the bed.. Marlin is set like this #define X_MAX_POS 180 #define X_MIN_POS 0 #define Y_MAX_POS 200 #define Y_MIN_POS 0 #define Z_MAX_POS 185 #define Z_MIN_POS 0 I tried to make Y max smaller didnt help.. and I Assume that is because that is not

Re: Prusa i3 Control Board Replacement - 9 years ago

thanks.. found one on Amazon.. so can you just swap out ? or do you need to do any config or firmware changes to make it work ?

Prusa i3 Control Board Replacement - 9 years ago

so lots of fun with my board.. not heating the bed.. replacing parts left and right.. next part the board.. image is my board now.. says MPX in one spot and Base v1.3 in another.. so question is.. whats the replacement.. cant seem to find a match.. I see things that look the same.. but say MKS... not sure what all the initals stand for.. just want to find a replacement.. maybe even get a board

Re: Heatbed issue - 9 years ago

130 ohms... so I put on the new thermistor.. still no heat power... so I assume something is wrong with the board ? whats a replacement one ? they all interchangeable ? on the board the only big lettering I can find says MPX 1 and BASE 1.3 one that I found looks to be the same layout.. but its MPX 3.. that a newer version ?

Re: Heatbed issue - 9 years ago

thanks for the continued assistance !! so Bed on LCD shows 16/0 Thermistor resistance on old and new show 130 ish I never looked at this before.. maybe it always says this when not heated up at bottom of LCD .." Err MINTEMP "

Re: Heatbed issue - 9 years ago

ok got my new heatbed in the mail.. smaller than the orig one.. but I hooked it up.. put the orig thermistor in it, because it had the 2 pin connector for the board on it.. the new one didnt.. still same issue.. no power to the bed... I hit set on Pronterface control but no power goes to the bed.. so if the Thermistor was bad what would it do ? make it not heat at all.. or just heat out of cont

Re: Heatbed issue - 9 years ago

This worked for months fine when my nephew had it.. and worked for me fine for like a month.. just stopped working the other day.. and the only thing I can think that maybe did it was when we hit return on the extruder and it started dragging the clip with it.. maybe it scratched something ? but back to the wiring.. its wired according to the chart.. it wants PIN 1 (+) and PIN 2 & 3 to be

Re: Heatbed issue - 9 years ago

Negative is on 2, 2 and 3 have a bridge and positive is on 1 which is how the pin chart shows it should be for 12v

by kevin_kss - Prusa i3 and variants

Re: Heatbed issue - 9 years ago

since 2 and 3 are joined anyway.. I assume I can use a 3 pin.. I attached the image

Re: Heatbed issue - 9 years ago

sounds good.. I guess I'll try that first.. but on that note.. mine on the back is a MK3 Heatbed Dual power.. so I see lots on Amazon... but mine is a 5 pin... all these I see are 3 pin.. this some new style and mine is old ? what do I look for to make sure its a match ? There model numbers on these ?

by kevin_kss - Prusa i3 and variants

Re: Heatbed issue - 9 years ago

if I do negative to positive on the hotbed leads I get .8 or 0.9 on the 200 setting on my meter.. I read if its below 1 then its bad ?

Re: Heatbed issue - 9 years ago

I'll try to check the resistance on it later today.. never did that before.. but on the board the only big lettering I can find says MPX 1 and BASE 1.3 I was looking for fuses before and didnt see them under the power bank at top.. so I guess it doesnt have them ??

Re: Heatbed issue - 9 years ago

QuoteI'm not sure what you mean when you said that you hard wired the bed with board current and when you put the negative on the wire got real hot. Where were you feeding the bed from? Also you shouldn't be trying to make connections carrying this sort of current with the power on. They don't like it. So maybe I did a No no.. but I just hooked in the hot to the main board power and had the nega

Heatbed issue - 9 years ago

So I just got a Prusi 3i from my nephew for my son..so we got it to print bunch of things since Xmas.. and then had issues with the filament going in and coming out.. So I took apart the extruder made sure it was all cleaned out and put all back together the same. We went to heat it all up and when it got to temp the wiring for the mk3 heatbead started smoking.. so we turned it off... looked at
