@EtherDais i do think you are having comparator issues, are you sure you have the offsets on the setting set to the same values? also, i would check your voltage from the regulator, no two are exactly the same, so maybe the voltage of the two differ slightly, i would first get a multimeter and start probing.by nutz4hs - General Mendel Topics
next chance i have ill sketch one up. its a very simple design so im sure it should go smoothly. as for the holes on the sides that mount it to the extruder block, i think it depends on the holes through your extruder itself, mine seems to be slighly closer together than some, and i have never had an issue with the tip slipping, i did however have a problem with the part delaminating by running tby nutz4hs - General Mendel Topics
@etherdais, i dont think they have released the stl file for the adapter, it was an old design, that under some issues failed so they are now using ptfe tubes as a replacement, although since the tip adapter is just a simple tube shape, it wouldnt be hard to dupe if someone required a part to temporally get the reprap printing. asking lambert may produce the file, or if needed, i may be able to mby nutz4hs - General Mendel Topics
just make sure to get the correct firmware for your extruder for repsnapper, or it wont report temps correctly.by nutz4hs - General Mendel Topics
@rista which model do you have? mendel or huxley? TZ is generally very bad at providing instructions for the machines (the instructions for their site link to a half completed and very un organized wiki),you are much better off looking around the forums and asking people as of right now, pennstate university is building a huxley and several mendels, and heavily documenting it, you might be able tby nutz4hs - General Mendel Topics
now that you've done all that, it definitely seems like a driver issue, most likely the serial-usb converter. i think we're in the same boat, but different states, im in Phila, PA but havent heard of anyone outside of expensive hackerspaces that have one. You can maybe try uninstalling the driver and finding a new one, its very weird to get it to BS instantly from plugging it in. good luck, illby nutz4hs - General Mendel Topics
just a heads up, i responded to this in your other thread about the tip adapter.by nutz4hs - General Mendel Topics
i've seen the other thread, i would bet the motherboard is damaged, i would try to unplug all connections except the serial and slowly plug things back in, even trying a new usb cable and checking the idc cable for shorts or bad connections, i hope you have a multimeter, if not theyre cheap and extremely handy for building and running one of these machines. I also went the route of using a 4th stby nutz4hs - General Mendel Topics
the white piece on top of the barrel is called the tip adapter, in the old kits they were printed out of abs, now theyre just chunks of ptfe tube, seeing as you dont have one, i can now understand your confusion. also, does your kit have metal bed springs or wooden? the old kits had wood and were prone to failure, they have now switched to metal ones, and if you have the old style, it may be a goby nutz4hs - General Mendel Topics
i hope these are helpful to you. like i said, any other help you need, don't hesitate to ask.by nutz4hs - General Mendel Topics
ok, i do still have it apart, so ill pull the camera now, the nut within the wood mod has worked very well, makes any extruder problem just that much easier. ill have the images up in a few mins. let me know if there's any other explanation you need. i built my machine with very little instructions, mostly 3 or 4 images of the parts completed, so i've made almost every mistake in the book. i onlyby nutz4hs - General Mendel Topics
@tom, what do you mean mounting? do you mean the oak block to the wades extruder? if so i have my extruder apart now and can take pictures, how ive always done it is by drilling the screws in to the oak so that they are at 90 degrees to where the screws would go to drill the tip adapter through the extruder, then drill the holes through the extruder as normal and use screws. as dazed said, the oaby nutz4hs - General Mendel Topics
sorry if this has been posted elsewhere, i cant seem to find any info about the problem i am having. I have been trying to build a tech-zone Mendel for a while and after all the rest of the problems handled. I have one problem that constantly causes more headache. I built the thermal hot end with a PTFE barrel and brass nozzle, i set the machine to 220c and after a few minutes the PTFE barrel spby nutz4hs - General
@jeffwilson, if your skilled with a decent fine tip soldering iron, you can cut the leads off the chip and use flux and desoldering braid to remove the old legs then buy a new chip (~5$) and just carefully setup the new chip, its not too hard, i was actually able to build my first set of gen3 electronics with only a decent soldering station and lots of time, might be worth the time instead of buyby nutz4hs - General Mendel Topics
@NewPerfection, thank you very much, changed firmware and all works, i'm actually able to use techzone defualt 5d firmware the unit ships with to use repsnapper out of the box.by nutz4hs - General Mendel Topics
not sure if this is the place to ask, but i just wanted to ask a quick question because this has been killing me, and its very close situation as the OP. im using techzone parts, with the newest 5d firmware, i can connect and move the machine in replicatorg and reprap host as well as read temp, but when i use repsnapper, i can move the 3axis(s) as well as the external stepper extruder driver butby nutz4hs - General Mendel Topics
