Re: auto leveling doesn't work - 9 years ago

2 questions. Is the bed properly secured to the carriage? Are you using 3 point or grid levelling? 3 point was a nightmare for me. Switched to 4 point grid and it worked literally first time.

do you cool or heat a pla print? - 9 years ago

Hi folks, Still learning about pla and its quirks. A little bit of confusion is occurring. It seems half the material I'm reading says cool the piece as it is being printed and the other half says don't. Any pointers or links to slightly less confusioning pages?

I think i was looking at using the terrarrium heaters so i could avoid reworking a 240v heater. Maybe i'll check around a bit more. Thanks

extruder acceleration/deceleration during printing - 9 years ago

Hi folks, Might be a simple question or might not. As the hotend moves around printing, does the extruder accelerate/deccelerate the feed rate of filament as it changes direction? Many thanks, Andrew

Re: pla constantly jamming in hotend - 9 years ago

Well, I've done ths tenp raise and didn't solve it. Switched over to my all ptfe hotend and oiled up some filament and the problem has completely vanished. Well except when the nozzle was jamming due to extruding too fast. Forgot that happens, I just hope i wont have to keep oiling the filament.

pla constantly jamming in hotend - 9 years ago

Hi folks, just got my first roll of pla to play with. I've gotten one 20mm hollow cube calibration print out of it and now it is constantly jamming right down in the hotend. I've run it at 200-210. My hotend is a custom job with a stainless throat, 30mm fan on the heatsink. This is my normal abs hotend with a fresh 0.3mm nozzle on it. It was extruding at <15mm/s If I manually force the fila

Re: overtemp heatbed for ABS a problem? - 9 years ago

Hey folks, I calibrated the thermistors tables again a few months, at least, ago with a stand alone thermocouple unit. But both the hydraptor and stock python table scripts stopped working. So i was only able generate a for table t=230° and rough estimate of 130° displayed equals 110 real. Imagine the suprise then when i hook the thermocouple the other day and discover setting the bed to 130 wa

overtemp heatbed for ABS a problem? - 9 years ago

Just wondering if a heatbed running overtemp, ie 130+, can be just as bad as a cool bed. Only just discovered the heatbed is out of whack and might explain why my first big print warped like crazy.

Re: angled striations on faces from extruder SOLVED - 9 years ago

Hi JamesK, Tried the diode array but ended with a stepper making a nasty thunking noise which only partially worked in one direction. Ripped out the DRV8825 and put a A4988(?) in and the ripples seem to have vanished. Never thought downgrading was the solution. Thanks folks

Just seems to be what it does going from layer 0 to 1. Though slic3r seems to be able to cool on the run and not pause anywhere near the same time.

Re: G28 misbehaving/behaving - 9 years ago

I guess just like waiting for the first service pack before upgrading Windows I think i'll wait for 1.1 to be out of RC. Having to issue G28 twice is at the end of the day just a quirk. Thanks Thinkyhead

blobbing during layer change/nozzle cool down - 9 years ago

Hi folks, Just experimenting with kisslicer and have a problem i knew would occur. During the cooling of the nozzle between layer 0 and 1, i am getting a blob of abs on the print. Is there a elegant way to deal with this? Say, moving the nozzle, during adjusting the temp, to an unoccupied part of the bed to dribble there. Any suggestions? Andrew

Re: G28 misbehaving/behaving - 9 years ago

The move to the centre of the bed is normal behaviour with a inductive sensor. I guess if I wan'ted to get fussy I could say the G28 works as it moves to 0,0,0. It is just the move from 0,0,0 to 100,80,0.9 that gets screwed up. Andrew

Re: G28 misbehaving/behaving - 9 years ago

After finishing a print and then G28 X Y the head ends up at 0,0,165. I issue a G28 to start again. Everything homes to my min endstops. Then it should advance to 55,77,0.9 which the GLCD shows. But without measuring it i can see it is around 10,10 etc.. It is offset because i have an inductive sensor and it moves to what it thinks is the middle of the bed. How 55,77 is the middle of a 200x2

Re: angled striations on faces from extruder - 9 years ago

Okay, just read the article, most of it went over my head at 30000ft in a 747. I was left with the impression that diodes are good and 12% bad. The circuit, almost too simple to call it that, is a walk in the park to install. I give it a go in the next couple of days. Obvious question, I can assume the people have played with changing microstepping and had no effect? Thanks JamesK, Andrew

Re: Pin define for RAMPS - 9 years ago

Hennezac, Could I guess that you are looking at hooking up a fan for PWM? This might be what you are looking for. #if MB(RAMPS_13_EF || MB(RAMPS_13_EFF) || MB(AZTEEG_X3) || MB(AZTEEG_X3_PRO) #define FAN_PIN 4 // (Sprinter config) #else #define FAN_PIN 4 // IO pin.

Re: Pause after bed reaches target temp - 9 years ago

Hey Steve, two ways to do this. Look for the following code in configuration.h #define TEMP_RESIDENCY_TIME 10 // (seconds) #define TEMP_HYSTERESIS 3 // (degC) range of +/- temperatures considered "close" to the target one #define TEMP_WINDOW 1 // (degC) Window around target to start the residency timer x degC early. Change the residency value to the length of time you want. Th

G28 misbehaving/behaving - 9 years ago

Hi folks The beastie appears to be working but I have issues with G28 misbehaving. The gcode for my prints finish with the following. G1 Z165 G28 X Y Nothing out of the ordinary here. My gcode startup has the usual temp commands and G28 G29 Still nothing amazing here. What is odd is everytime a print starts and runs the G28 it homes to zero correctly. But it then only moves 1/3 of the way t

angled striations on faces from extruder - 9 years ago

Hi folks, just about got my head around using Kisslicer, must say I like it a lot. I've been working through calibrating the extruder by adjusting the flow tweak. I've noticed an interesting problem with the printed surfaces. They have angled striations that change depending on settings. Now I know this is caused by the extruder because as I adjust the flow tweak the angle and density of these l

Re: Prints skewing to Y max - 9 years ago

I checked the wobble in carriage after printing honeycomb the first time. That was scary. The wobble seems to be limited to that introduced by the linear bearings in the x carriage and the z axis. If i inspect the visible layers in the z, they appear consistent with no areas of poor adhesion. Well except when they are all poorly adhered! Inductive sensors are sooo worth getting! The steppers
