Ahem, I think I overvoltaged my V+ rail of my RAMPS 1.4 via a short circuit, this was fed into the RAMP boards rail via a loose Z min endstop V+ cable. So far I think I have blown the voltage regulator of my LCD shield, however any ideas what else might have gotten damaged by 17v voltage to the RAMPS ? Steppers + Arduino / RAMPS all seem fine so far, end stops all work. A bit surprised honestlyby cannonpr - General
Generally speaking, anything you can dissolve PLA in, you really don't want in your home. Chloroform asides from being implicated in heart failure is carcinogenic, also if you spill it, it can quickly evaporate, knock you unconscious and yea... Read and generally for finding information on this you will have better luck by googling "Solvents for PLA" PLA and several co-polymers advertised as Pby cannonpr - General
Found that my self recently, Personally I suggest you search for G29 in the gcode and disable the deploy and retract zprobe functions, those along with the coordinates belong in slic3rs pre-gcode, not hard coded into marlins main cpp. You can just add them as G1 commandsby cannonpr - Delta Machines
I am using a modified HP server power supply, 12v up to 62 amps, very stable and showing 12.08 voltage when measured under expected load. Using Marlin firmware. Programming the Arduino without the ribbon cables mostly works fine but even then shows random errors sometimes, no difference when powering it from USB or powering it from PSU. @Coherent: What do you mean by hooking it up to a second ardby cannonpr - General
I wish, endstops verified and correct, using Hall sensors.by cannonpr - General
I recently got a RUMBA board, I was wondering if people have had issues with it, My main problems so far: 1. Random behaviour with the endstops triggering on and off 2. Completely unable to flash Arduino with Ribbon cables for a controller attached 3. very frequent connection errors with PrintRun 4. Steppers randomly increase or decrease speed 5. Arduino seems to randomly reset during operationby cannonpr - General
Did you ever find a solution for this ? I am experiencing fairly similar issuesby cannonpr - Delta Machines
I am wondering if you had any experience with rather extreme diameter variability with filaflex. Both spools I have gotten off them show anywhere from 2.6 to 3.1, yes I am very careful with my calliper measurements to avoid any compression. Also showing an extremely oval profile in certain lengths. I use an e3d nozzle so anything above 3.05 generally won't fly, it's bore is quite tight.by cannonpr - General
Since a lot of them seem to contain Sodium Silicate I suspect part of the action is that it causes micro abrasions to the glass during cleaning.by cannonpr - General
This is the stuff I used: The appeal to me is that it doesn't leave a mess, most glue sticks do after time, especially with dust build up etc, also the adhesion is a lot higher than any glue I have tried. I have on occasion suffered from edge lift based on the glue stick used.by cannonpr - General
Hey, Has anyone else experimented with cleaning/treating a common glass bed with strong sugar soap ? I have been getting some pretty interesting results. Adhesion for PLA was strong enough that I broke my first bed accidentally while trying to detach. Similar results on ABS, curious to try Nylon and other materials now that normally don't attach to regular glass. I understand it's a common deby cannonpr - General
Have a look at They went with a liquid cooled solution, I have to admit it seems more sensible than mechanical linkage transfer.by cannonpr - General
Self printing thermal chamber ? A few people have played with this before, probably captures and keeps hot air from the printbed.by cannonpr - General
So Prusa goes exactly the same way as everyone has done previously to give it enough cooling area, while tweeting about it merrily. elgambitero Wrote: ------------------------------------------------------- > woodencase01 Wrote: > -------------------------------------------------- > ----- > > I don't know if anyone have seen this picture, > but > > it looks exactly like tby cannonpr - General
I managed to get mine to work to be fair, but I actually attached a water cooling rig to it to get PLA to work... Haven't heard back from Prusa on e-mail in a while even though I got a quick reply initially.by cannonpr - General
Hey, So, 3 reprap printers later... maybe I should stop making new ones but, has anyone made one of these ? Patenting issues asides(with the enclosure and stratasys) it is a fairly new project and I am wondering if people expect snags with their existing documentation, to make one from scratch without a kit.by cannonpr - General
Hey, Actually for me I found out that a high speed polishing tool such as a dremel cotton buffing wheel of any variety works really well for polishing /smoothing PLA. Sandpaper on a dremel tends to melt/destroy the plastic however a cotton wheel seems to remove Z lines very well. Just keep the object cooled with a fan while doing this and ensure you have printed with 2+ walls so that you haveby cannonpr - General
Hey kludgineer just to clarify, I do not consider this a Repstrap, just that it is uniquely suited for a Repstrap, I am still waiting to see the printable files my self. I rather like the design and I am waiting to see the rest of the details the MendelMax 1.5 is an excellent design and I don't expect anything else of this one. That asides, the cartesian robot is just about as old as the industrby cannonpr - General
Hey, I assume that people have by now noticed MendelMax's announcement for 2.0 I was hoping to see what people think regarding the new design, and the feasibility of printing one versus building it as a rep-strap, the announcement mostly mentions ease of assembly and manufacturing benefits so I am assuming that there is no resolution/quality change versus the 1.5.
