Yeah they don't switch out.by zomie - RAMPS Electronics
Well, I ordered another ramps board and arduino combo and am getting the same issue. It is very damn odd. I even disconnected the ramps board and left the arduino bare and I get the same readings back on the new arduino. It is defined as board 33 too ... Any other ideas?by zomie - RAMPS Electronics
Well I have ordered from them twice and they have always had amazingly quick shipping. The second one I ordered was a Mark IV Jhead .5mm nozzle for 1.75mm filament. I installed the hotend and the filament kept stripping and the flow rate even when reduced really low wouldn't feed right. I emailed them asking for advice on how to repair the hotend or for help to see if I had installed it incby zomie - General
I just got a j head IV from hotends.com (nice machine work btw). I am having serious issues with flow rates with 1.75 pla (actually around 1.63mm). I can only seem to get it up to around 20m/s using a gregs accessible extruder from 185 to 205 C. Most of the time it is stripping the pla or if I apply to much tension grinding through the filament. I can push the filament through by hand but onlby zomie - General
I can't seem to close this out, but I managed to solder parts from 2 bad pololus into 1 to get something until replacements come from denmark.by zomie - California, San Francisco Bay Area RUG
Today, I got in a new hotend after a therm disaster for my Pursa. I assembled everything and attached a new small 30mm fan to the hotend grills to chill it off as directed for pla. Well like an idiot in my rush I added electrical tap around the pot's electrical leads after soldering them which i set up for speed control. Well of course as soon as I turn it on and it starts printing the potby zomie - General
I fried one and am looking for a replacement. I would rather buy locally. I am in Santa Clara. Drop me a note ... Jamesby zomie - California, San Francisco Bay Area RUG

Just a follow up ... I unplugged the ramps board and tried wiring a thermister to gnd and analog 8 10, 13, 14 on the arduino. I am pretty sure it is a dead board as the readings never changed.by zomie - RAMPS Electronics
I am getting the following read out in pronterface: ok T:135 B:357 The odd thing is that I get the same even if I unplug the thermisters. It is like it isn't even picking up a temp reading from them at all. I verified the pin layout from: which is in sprinter. I am not sure how to proceed? It is on a knock off Ardunio mega 1280 running sprinter firmware. The board is driving the motorsby zomie - RAMPS Electronics
Has anyone came up with a good recycling process yet for reprap misprints? I only found the following: It seems like it is still in early development. Is there anything else out there?by zomie - General
Basically you guys are right ... The damn plastic bearings that came with the kit were binding horribly. I would free it up and the other side would go. Eventually I managed to drill both out with a 5/16 bit several times to get it to run long enough to print this: Thanks again! You guys are always on target.by zomie - General
I wrote him about this and heard back: Brook Saturday Nov 19, 12:00am EST I will actually be releasing the files open source before the project funding date. Frankly, I make little improvements to the design almost daily... I am very keen to put out quality design where everything just works. My real "market", if you will.... the people I really want to reach are the ones without a printer... tby zomie - General
I love how bloody simple the design is. It is very easy to upgrade the axis movement too. I think they may drive the huxley at least to extinction. The only issue I have is I can't find the darn files to print one myself Their website:by zomie - General
I finally fixed a jamming issue from my wades extruder and have started getting down to some printing. Sadly though I appear to be getting this odd offset prints where it seems to be wider on one side?! The fill isn't then filling in on the side of the print. I was curious if anyone had any suggestions. Here is a photo: I double checked the belts and they are tight and the carriages movby zomie - General
I think you guys may be on to something about the hobbed bolt. It is actually pulsing on extrusion. It will pull 1/3 of the time and then it won't move. I am guessing the bolt has a flat spot in it. My huxley just provides constant force on the filament. I am thinking that as it is pulsing it provides extra pressure striping the filament. I am going to print out a new wades accessible extby zomie - General
Hmm interesting ideas ... I didnt' realize the hobbed bolts come in different sizes? I figured it was all about the pressure between the bearing and bolt. It is certainly strong enough to tear apart the filament and strip it. Yeah I apologize. I have the feedrate set in Pronterface at 300mm/min which I thought was pretty standard. It doesn't actually make it all the way through 100mm. I meby zomie - General
I put together my Prusa Mendel but I am having some bad feed issues. I am trying to use 1.75mm filament, and have a J head IV setup for that. The only catch is the wades extruder has wider holes for 3mm filament but I don't think that is the issue. If I run 100mm through the extruder it will slow down and stop then the bolt will grind out filament and won't feed any more. I then have to takeby zomie - General
Here is how you change the amp on the drivers: 2: Axesby zomie - General Mendel Topics
Make sure you have the zaxis wired correctly. The motors will just hum or beat back and forth if one of the wires isn't connected. The other thing to check is the power output from your drivers is enough. They should be putting out around an amp or so.by zomie - General Mendel Topics
I figured I would share some customer feedback about a mid US reprap dealer. They are based out of Colorado so they provide some extremely quick shipments across the west which is great when you are in CA and have been ordering parts from Europe for way to long I ordered from them in the past for emergency fixes such as electronics which I accidentally fried. They shipped same day and overniby zomie - General
Yep figured the darn thing out ... it was a connection issue but from the assembled board I purchased from a US vendor (emailed their QA dept about this). You can see for yourself in the attached pic: They missed soldering one of the leads for the z axis. It seems to be working like a champ nowby zomie - General
I don't believe so ... I attached a screenshot of it. I turned it down from 200mm/min to 20mm/min and it had no affect. I also attached my conf.h Any other ideas?by zomie - General
I plugged the motors into a separate driver circuit (extruder) and they work fine. I then plugged the extruder back into the zaxis port and it started shaking just as bad. It is sounds more and more like the ramps I purchased is trashed?by zomie - General
I am having some pretty serious issues with my z axis. It basically just shakes not moving properly in either direction. Video of it screwing up: This is on a Prusa Mendel. I am using sprinter firmware and a Arduino Mega 1280 with Ramps 1.2. I am running the latest Pronterface.
