Hi folks - I've been having trouble restoring files from the local Library on my PC. MC seems to save well enough but when restoring (no matter what file size or complexity) MC just exits. Even just clicking on the icon in the Library spins up my CPU before crashing. Any suggestions?
I am afraid we do not see the photo you are trying to upload, could you give it another shot?
Generally, you would want a first layer to look flat and "Squished" together.
I look forward to seeing the photo and helping out!
Suggest you call tech support on this. I know hobby king sells belts and they are sold as 3d printer belt cause seems like they all use the same size - but I'd call MH just to make sure. Otherwise mine loops through the bracket and flips ove on itself so its own teeth engage and you either got a bracket or a zip tie or something like that to keep it engaged
Have not done Nylong but sometimes that happens to me with other Nylons so...
1.) I print most Nylons with bed at least 80
2.) Big Brim
3.) Up the extrusion on the 1st layer
4.) Decrease the Z offset to press the first layer harder into the bed but not so hard that the extruder skips. If you just print one layer the sheet should not come apart at the layer lines.
I slice with SLIC3R and when I print with a .4 with .2 layer height I print the first layer at .52 and .96 layer width and turn the Z down at least .2 and that works most of the time. Also its summer and it might be humid so dry out some dessecant packets in the oven and 250-275 for 2 hours and throw them into the print dry so you are not blowing hot wet air around the filament.
Also would be interesting how the Gecko sheets work with Nylon Tried to ask a question here in another thread about that but no answer....
@lpinney motors (all of them) generate heat from being powered up.... BUT they cool off when moving due to air flow past the moving parts.
unfortunately if they stop moving the heat cannot dissipate and they heat up.... a problem with this is that the hotter they get the lower the coil resistance, more heat = lower ohms = more heat = lower ohms etc etc... otherwise known as thermal runaway.
ok so that explains the over heating... now its simply(???) a case of why has it stopped turning... something jamming it? friction or foreign matter in the extruder feed/ gearing?....
the flattened filament is probably simply due to the overheat which coupled with no movement causes heat deformation.
likely causes are blockages, foreign matter in the motor/ extruder interface (good posh word that is) or an underpowered motor.....
good luck with the search
Do you have a printer setup and profile for cura for the pulse? If you do can you possibly share it? I got one form Matterhackers last year but it sent my hot into the bed so I put the printer back int he closet again. Its been a year - so its time to try again....
No cause MC did not go down in the power failure only the printer as mc runs on a laptop with a battery. Here test as follows
Connect to Pulse with MC
Start a print
Unplug printer and plug it back in or turn it on/off like in a short power fail
Watch it crash as soon as the Boot screen disappears.
Problem is the printer does not say "Hey I am back up" and MC did not time out or something and just keeps sending Gcode as soon as the connection is live again.
Tried that - within 75 mm of center. If you tell me where I send you some STL's set to turn fan on if print time < 30 sec. Slice with a slicer of your choice tried to upload them here but it tells me I don't have the priviledges. they are 15 tooth htd pulleys. Or print 3 16mm tall 18mm diameter cylinders with a 13mm hex hole in the middle at least 2 in away from the edge of the plate as the edge does not carry the temp and set the fan to 100 % heck even 50 % does the trick. And just to make sure it isn't something melted on the hotend mount I reprinted that. when I installed the new E3D V6. Alternatively create a circular plate 196mm in diameter 4.8mm thick with a 29mm hole in the center 4 6mm holes on a 50.4 mm circle and 6 8mm holes on a 112mm circle and print it with a .8mm nozzle and .4mm layer height - sold (6 bottom, 6 top layers and turn the fan to 50 % and a nozzle tempt of 275 and roll the dice who is going to have a thermal runaway first the nozzle of the bed. So either there is something wrong with my printer or it just cant do it. The solution to this one is to turn the fan off and slow the print speed quite down. Heck this one even fails with PLA and the bed at 85 to get a heat resistent annealed dimensional correct pla sheet. It becomes particularly challenging with low bridges that need a fan on pretty much any material like this
Both will cause a Thermal runaway on the bridging when printed in HIPS (270 nozzle 100 bed) The 2nd item luckily can be printed on a 45 deg so there are less bridges (its 267mm lon and prints diagonally) the first one is 215x167 thereabouts and the first bridge section is 13mm off the plate. Only choice on that is set bridging fan to 10% and design it so its about 1mm lower than need be so you can file a lot of hanging stuff out to get it dimensionally correct. (first part also is about 180mm tall). So anyone know a change to the design that would allow better bridging and cooling - I am all ears. Until then this is just for anyones info. If you got a pulse and need to bridge at high temps close to the building plate or print small items - do it without a fan or with the fan at < 20% depending on distance from build plate. BTW both items are used in multiple configs on the "bumblebot" I posted here
The DXE doesn't have EEPROM - that's only for the 8-bit electronics.
You can adjust steps/mm on the DXE, but it's a different procedure. You just need to send the appropriate G code to change it.
Though, based on what I see, I don't think retraction is the issue here.
Give me a call or reply to our last email and we can troubleshoot the PLA issues in more detail.
I would highly recommend if you have not already reached out to us at our support line of firstname.lastname@example.org or our phone line of 949-613-5838 you do so. We are more than happy to figure out what is going on with the printer and figure out what happened. We will need to clarify and if possible get videos of what you have described as there are multiple factors that can cause what you have described and seeing exactly how the printer reacts will point us in the right direction.
I have crossed out the recommendation from Martin as I do not agree with his input on this matter. There are a number of factors to consider and my team and I would want to take a closer look before we recommend any further action.
how long has this bug been active?
I did an update months ago and then got rid of my Makerbot because my PC quit talking to it. I blamed it on the Makerbot update.
Now I have a Tevo Tornado. And when I connect it automatically recognizes it as a "RAMP" on the port. But wont act. My arduino wont compile because it doesnt see the printer. And when I look at the driver properties, its a matterhackers driver.
I uninstalled matterhackers slicer months ago. NO other slicer will work either. Likely due to the driver.
Your thoughts on this?
@mpirringer said in So let down...:
Hotend mount needs to be redesigned and printed out of something that is not RYNO currently some of the parts I printed out of HIPS namely the ones that are close to the bed - otherwise you do a big hips or ABS prit with the bed at 100 and the bottom of the fan shroud will deform from the heat of the bed. The fan even when perfect blows too much onto the nozzle or the bed you can't keep the nozzle at 270 and bed at 85 + if the fan is at 100% 60% max will work at any temp. The leg of the BL touch is unprotected and I currently level manually as every time a print comes loose I lost a leg and replacing it 3x is enough for me. The wires in the back of the heater block also need protecting so that should be designed differently too.
Thanks for all the info! yeah I lost a few bl touch legs too, I ended up designing a small switch that would raise a magnet and springs would pull the touch down and then after leveling would lower the magnet and pull the sensor back up just a few mm and that seemed to be a nice tweak.
Looks like your connection to MatterHackers Community was lost, please wait while we try to reconnect.
