Re: Prusa I3 Z axis problem - 9 years ago
My apologies for not being that descriptive, I just use the picture as a reference. My X end stop is a max (Like the pic) My Z is a min (like the pic) but my Y is a min (different from the pic). My home position is diagonal from the one in the picture. I have all the switches pluged in the right spot on the ramps board and also configured right in the firmware.What I think is causing the problemby Stack - General
Re: Prusa I3 Z axis problem - 9 years ago
So generally speaking, when I move the motors in pronterface in the positive direction they move: X: to the right Y:backwards Z:up Is this right? According to this picture I have my end stops set up in the firmware and on the board as: X:Max Y:Min Z:Minby Stack - General
Re: Prusa I3 Z axis problem - 9 years ago
Quoteo_lampe Have you checked the two z-sides, if they run parallel? I found my M5 nuts on the z-leadscrews were not aligned and all the weight rested on one z-rod. That can cause noise too. I have and I printed out a spool holder and it came out great, But I ran in to another problem, I tried to print an arduino holder but it came out mirrored and the board wouldn't fit.

Quoteo_lampe Quote#define DEFAULT_MAX_FEEDRATE {500, 500, 5, 25} Change this line to : #define DEFAULT_MAX_FEEDRATE {500, 500, 3, 25} This will make the stepper work again. With "5" it was to fast ( and noisy ) I changed it to 3 and it really helped but was sill a bit loud and then changed it to 2 and now it works like a dream runs smooth and homes like it should.

Re: Prusa I3 Z axis problem - 9 years ago
So before I went in and changed the default steps per unit for the Z axis, i printed the one on the right, my j-head hot end was not raising high enough for the next layer to print and squished the entire print. Then I went in and only changed the default steps per unit for the Z axis to equal 4000 and re-flashed it. Before I changed anything, The z motors worked great and ran smooth and the endby Stack - General
Prusa I3 Z axis problem - 9 years ago
So I've been having some troubles with my prusa i3's z axis. My first print was all smashed by the hot end. I went into the Marlin config file and found that the default steps per unit were set at 2000 when its supposed to at 4000. I change the default steps per unit from this: #define DEFAULT_AXIS_STEPS_PER_UNIT {80, 80, (200.0*8/0.8), 700} #define DEFAULT_MAX_FEEDRATE {500, 500by Stack - General

Re: Prusa i2 or i3? - 11 years ago
I found this site for the Mendelmax and its really great but its missing the threaded rod and the smooth rod. It looks like he has everything else. Is he missing anything? And what rods do i need.by Stack - Reprappers
Prusa i3 Frame - 11 years ago
Hi, Its me.... again. I was wondering where I could find the files for the prusa i3 single sheet frame and where I could get them cut. Also what kind of material should be used because I've seen where the acrylic ones have some supports and the aluminum ones don't. If anyone also knows of a current list of hardware for the i3 single sheet frame that would be wonderful! Thank you so much! -Sby Stack - Reprappers
Re: Prusa i2 or i3? - 11 years ago
I can find the misumi extrusions but for the printed parts i cant find much anywhere. There is also no Bill of materials, though my guess is that the electronics and stuff are the same. I like the design of the mendelmax and want to make it but cant find a list of the things needed. If anyone knows where to find a list or something and not the one on the mendelmax site because that one is reallyby Stack - Reprappers
Re: Prusa i2 or i3? - 11 years ago
Well the mendlemax looks like a great build and so does the i3 but self sourcing that is not going to be easy and both are a bit more pricey then the i2.by Stack - Reprappers
Re: Prusa i2 or i3? - 11 years ago
So you wouldnt recommend a prusa i2 to anyone anymore? The top repraps are the Prusa i3 and MendelMax?by Stack - Reprappers
Re: Prusa i2 or i3? - 11 years ago
Are you losing anything with a medelmax? Like build area or anything? Also can you use like Wades extruder, a J-Head hot-end and RAMPS 1.4 with it? Thanks, -Stackby Stack - Reprappers

So you recommend the mendel max 1.5 or a prusa? I don't completely understand..by Stack - Reprappers
Prusa i2 or i3? - 11 years ago
I recently asked a question about a J-head hot-end. Thank you all for the help on that! I know this question probably gets asked a lot but, what is better the i2 or the i3. What is best for a first time repraper? Maybe like what are some pros and cons from both? Thanks!, -Stackby Stack - Reprappers

J-Head Hot End. Help? - 11 years ago
So I was thinking of getting my J-head hot end as a kit from makerfarm (link below) and was wondering what the the install kit for ramps was for. I plan on using RAMPS 1.4 for my electronics but, do I really need the 40 W Ceramic Heater kit. It says its for RAMPS but I have no idea. Store Link- Thanks, -Stackby Stack - Reprappers
