lance-greene

so if i was printing multiple of the same L shaped piece, i shuld be able to place them very close together for multiple prints, but cura wont let me. i can do it with makerware though. is there a way to do this? cura puts a shadow around the part and wont let you place another part within that shadow.

im just wondering if you can skip the initial nozzle purge at the beginning of a print and just use a skirt to prime the hotend. i cant figure out how to turn the purge off

i solved the issue. when i spliced the connector to extend the length of the wires, the connector i used was from a stepper motor for a different printer we have, its connections within that connector were positioned differently than the ultimaker and signals were being crossed. i corrected this and it prints perfectly now.

i dont think this is the issue, ive never had this problem before, the only new thing is the motor. all the pullys are the same as before

ive managed to align the belt properly. thanks for the help

so my x axis stepper motor failed, i got a new one from robokits in new zealand that is the exact same as the ultimaker one and replaced it, i had some belt alignment issues but fixed them. now when i run a part, as soon as it starts printing it jiggles very heavily and is entirely unprintable. the cable for the motor was too short so i cut some extra off the old stepper motor and soldered them together, connecting the cables all with the same color wires, then put electrical tape on the soldered points to keep them from touching. i dont know what the problem could be, is something wrong with the firmware controlling the motor maybe? i dont know.

i only inverted the pulley on the motor. ive tried moving the pulley back and forth along the motor shaft a little bit to try and align it better but it still happens. ive tried loosening the pulley on the x axis shaft to help align it and it hasnt helped. i wasnt having this problem before i replaced the motor either.

i did that, and now it is more aligned, but when i tighten everything up and slide the hot end back and forth, the belt sort of wobbles like the pulley is egg shaped or something, it rotates fairly smoothly, but you can still feel a bit of tugging as it tightens and loosens with each rotation. any thoughts?

so my x axis motor failed an ive got a replacement from robokits in new zealand n(its the same stepper motor ultimaker uses. when i installed the motor i noticed the belt doesnt align properly, anyone know why that is? should i just put some washers on the mounting bolts to try and bring the motor into alignment? i made sure that the gear on the rod is pushed all the way to the bearing and it still wont align properly.

so I have a geeetech G2 delta printer here that prints mostly fine aside from 2 issues i cant seem to solve. 1. the extruder motor constantly skips back while printing. this generally happens with the motor is putting too much pressure on the filament so it slips back to prevent damage. the skipping causes almost no actual degradation to the print surface and the machine prints mostly fine even with the constant skipping. I've adjusted all possible slicer settings to help reduce this back stepping but it wont stop. ive adjusted the voltage on the motor controller as well and it didnt seem to help basically im wondering if perhaps i can adjust the firmware controlling the motor to help it? but its the only idea ive come up with as ive tried all slicer adjustments i can. 2. each horizontal layer has about a layer wide gap between each other horizontal layer. so if i print with 3 perimeters each layer has quite a large gap between it and the layers beside it. ive tried adjusting all the slicer settings i can including nozzle settings and nothing has helped. so i assume this is a firmware issue as well? any help?

It's the first time when I hear that .... I think it's a bad quality piece of glass :( There are a few materials on the market that can suffer from this effect of pulling pieces of the glass out. T-glase from taulman suffers from this effect as do a few other materials on the market. i would highly recommend with a material like this to either remove the part from the buildplate as soon as the print is done, or have the plate stay heated until you are able to remove the print.

its caused by leaving the print on the bed while the print cools. to prevent this from happening, remove the print before the bed cools down

i found makerbot produces a filament like this, does any other manufacturer make a filament like this?

Hey i remember seeing a filament that prints solid, but when heated in water becomes flexible and will keep its new shape once cooled, anyone know of this? i tried googling it but couldnt find it.

actually i found the best deal is a website called http://www.robokits.co.nz/ they had them cheaper than anywhere even with shipping included. ultimakers canadian distributor had to order them from a warehouse which takes 2 or 3 weeks plus then shipping to me all while costing more than this UK company to bring it to canada

the motor ended up not fitting properly, is there a list of info i need to know about the stepper motor in order to buy the right one from a company that makes them, cause there are some in canada and the distributor here is out of stock for a few weeks and I really need it as soon as possible.

so the x axis stepper motor on my machine failed and i need a new one, the only canadian ultimaker supplier is out of stock and i found other suppliers with stepper motors but i have no idea how to determine what will work as a replacement or not. my friend gave me a stepper motor from one of his delta printers but i have no idea how to tell if it is the proper motor or not. it has the same sized faceplate (nema 17 i believe) but the body of the motor is also a bit longer than the ultimaker motor here is a photo of the stepper motor he gave me.

i got this stepper motor off a friends delta printer, can i use it as a replacement?

so the X axis stepper motor on my machine failed, its really hard to turn and it sticks and feels nasty while trying to rotate it, i assume the bearings or something failed (i plan to take it apart to check it out later). although at 1300 hours of print time im not upset about it. but i'd like to know the specs of it so i can order a new one. i took a photo of the ID tag on the motor but its in an arcane language and im sure the ancient sacred text to translate it has been lost in a deep forgotten catacomb. why does ultimaker not sell the stepper motors their printers use on their website? even their canadian distributor (im from canada) doesn't supply them.

so I know ultimaker doesnt officially support dual extrusion, but you can just buy the parts and throw it in your machine if you want. im just wondering if anyone out there is doing that and what their results are like? I know it will require some fiddling with the machine but I'd just like to know if anyone doing it is having success with it.

i use elmers extreme from walmart, it should be with all the other glue sticks

i set the initial layer speed to 50 mm/s which i know is fast but the increased flow rate is able to compensate for it. i find bondage between layers is still pretty bad if i dont increase the flow rate though.

could the problem be filament slippage at the feeder? maybe the tension is set wrong?

the layer bonding is perfect. i can stretch the headbands out quite far and there is no separation. the increased flow rate and 260 degree temp is the main reason the layer adhesion is so good. also the super slow print speed helps a lot as well. i noticed that on the very top layer, some of the perimeters look like they have fully melted together because of the hotter than normal temps i used which is another good indicator of good bonding

so ive had my machine for about a year and a half now, ive printed around 1300 hours on it and it's been printing like a dream since I got it. i regularly lube the rails and use the supplied grease on the z axis. yesterday i started to notice that sometimes i get a high pitched squeel coming from the machine whenever it moves along the x axis, i cant tell if its the bearings moving on the rial, or if its coming from the stepper motor itself. when i turn the machine off and move the hotend it moves fine along the y axis but on the x axis it basically doesnt want to move, which really makes me think its something with the stepper motor but im not sure. even though the hotend seems stuck while trying to manually move it while the machine is off, it moves fine while printing. any tips?
