I upgraded to v1.0.6, but still have the issue. Seems to be something specific to me then...by Stephanel - Repetier
QuoteBrainSlugs83 Downgrading to Repetier Host 1.0.6 fixed this issue (as well as a few others) for me. In 1.0.6 there's a draggable bar in the regular slicing window (right below speed -- not in the options), if you set that to the desired amount and hit slice, it just works. -- That bar might also be there in 1.5, and maybe I was being dumb and had it set to 0 or something ridiculous, but I doby Stephanel - Repetier
Quoterepetier You better reread your image. That is the infill density of support not the one for normal infill. Normal infill can not be set in that settings. It is only available in the right tab with the slider called "infill density" where you also start the slice. Correct! Sorry about that! However, I did have Infill Density at 40%, and tried it again just now. It does not work (anymore) inby Stephanel - Repetier
Hi! My infill density is at 40%... Maybe there is another setting that sounds off? These are my current settings:by Stephanel - Repetier
Hi! I am using since quite a while Repetier Host to control my 3D Printer. Normally, I used Slic3r as slicing engine, and that worked OK. However, it appears that Slic3r has some difficulties with more complex objects, and then includes a bit too many travels in each layer, resulting in bad prints. So, I tried to use the CuraEngine. I used it before, and indeed it resulted in faster prints. Howby Stephanel - Repetier
Hey all! You are great remote trouble-shooters! It seems indeed that the reason was that the MOSFETs were touching eachother. I carefully moved them a bit apart, and now all is working perfectly! Fantastic!! Thanks a lot to you all!by Stephanel - RAMPS Electronics
Hi there! Thanks for your thorough analysis! I am abroad now so not able to work on the printer right now... At E I changed the 3d model. The first one had a larger base while the second had a smaller one. As you say, I also think it's a hardware problem. I will definitely try to do what you suggested! Thank again and I let you know my findings (probably next week only...)by Stephanel - RAMPS Electronics
I have a separate 12V power supply... I have exchanged the RAMPS board and still I have the same problems. The temperature reading seems OK. Indeed, it might be that the power supply is the cause, but then I would expect the bed not to heat up at all, instead of keeping heating?... I set the setpoint and somehow my RAMPS board does not seem to recognize this and switch off the heating power?...by Stephanel - RAMPS Electronics
Hi! For some reason, since a few days I have a big issue with my RAMPS board. I don't know why, but when I print, after a while, the heated bed becomes hotter and hotter. At first, setpoint is reached nicely, and things settle down. However, after a while, the readings get hotter, and keep increasing. I once reached 110degC with my setpoint at 60degC. Obviously, I shut things down, as I do not tby Stephanel - RAMPS Electronics
Sorry for the late answer, I was abroad, and not able to work on the printer... Thanks for the suggestions! I however tried 0.3, 0.35 and 0.4mm as layer thickness. All seem to have similar issues that the print is being pushed down by the nozzle. If I watch closely at the second layer, I indeed see that the heated bed is being pushed down (1/2mm or so) by the nozzle. That doesn't seem right to mby Stephanel - Delta Machines
I have a layer height of 0.35 and a nozzle of 0.4mm. I can set it to 0.4mm, if that would help :-) I did some more tests with other prints, and apparently it seems that the print that did not work was a bit special. It had a lot of support, and that support actually came loose. Printing a full product (with limited support) seems to work better. I also tweaked a bit the Delta Radius parameter, sby Stephanel - Delta Machines
Thanks Andy! Sadly, I indeed checked that my belts were OK and that the carriage moved correctly. The extruder also extrudes at the correct pace... The problem seems that the accuracy of the calibration of my machine is not sufficient to print more than a few lines... Or maybe I'm just looking in the wrong direction...by Stephanel - Delta Machines
Hey! I have a problem with my delta printer that hits the printed material. This only happens when I have printed a number of layers. Apparently, the nozzle hits solidified material, and then misses some steps. From there on, the print is screwed... I calibrated the printer already numerous times, and as far as I can see, it should be correctly calibrated. It seems however that the print head dby Stephanel - Delta Machines
Sorry! Rookie mistake! I should reload the firmware, or set M95 Exxx :-) Now it has changed!by Stephanel - Delta Machines
Happy to say that my printer is back printing :-) Another issue that I have is that the Bowden extruder will sometimes hickup (it will go back a step). I thought I could calibrate this by setting the setting in Marlin firmware: #define DEFAULT_AXIS_STEPS_PER_UNIT {80, 80, 80, 120} If I set the 120 to a lower value, I should be able to solve the too high feed rate. However, for some reason,by Stephanel - Delta Machines
Sorry :-) Indeed, it is the long one that doesn't work. The right one has the 0.3mm opening, so I would have expected it to extrude less easy as the left one. However, the left one just could not get things through. I tried 2 of them (both new), but it seemed not to work at all. The second indeed has a gap between the nozzle and the nozzle throat. This resulted in severe leaking, which I solvby Stephanel - Delta Machines
Thanks! I replaced the hot end nozzle from top to bottom in the picture below. For some reason, the top one always blocks up (also with another similar one). Now, I could manually push it through. On top of this, it appeared that my bowden extruder driver was not calibrated correctly, and I had to adjust the potentiometer to provide more current. After that, the extruder could push the filameby Stephanel - Delta Machines
Thanks! The nozzles were brand new, never used. I indeed also tried at lower temperature, to no avail... It seems odd to me that before I never had any issues with extrusion, and could push the filament easily through the nozzle. Now I need to put excessive force to try and force it through... Maybe another clean might help, but how would you suggest to do this? There will always remain a bit oby Stephanel - Delta Machines
Hey! Some weeks ago, I was able to print very nice PLA objects. Then I tried to move to ABS, but things went horribly wrong. I overheated my hot end, and since then I did not manage to print anything anymore. In the mean while, I have exchanged just about everything, including the hot end and even the RAMPS board. Basically, where I am now stuck is that I still am not able to print anythingby Stephanel - Delta Machines
I have changed the PID settings, and restarted the printer from beginning. I input them in the firmware and ran the M301 command to make sure that the PID were loaded. Still however, the extruder temperature will not go over 240degC if I set the target to 250degC. It keeps on hovering around the 240degC mark...by Stephanel - Delta Machines
It is very strange. I never tried to do a heatup to 300degC, as I didn't want to risk it. However, now I did, and for some reason, the heater could get to 268degC (after which the program reset, as this was max temp). Then I reset the setpoint temp to 250degC, and it just would not go over 240degC... I did however do the measurements: ve+ - ve+ = 0.26V ve- - ve- = 1.4V As you say, this might iby Stephanel - Delta Machines
The resistance is 4.3Ohm ... So it seems like it's a 12V cardridge heater...by Stephanel - Delta Machines
Quotedougal1957 QuoteStephanel It is probably like you say, the cardridge heater seems not to be able to heat the block up to 250degC. I have increased the power supply voltage to 13.5V and the supply at the RAMPS board to the extruder now reads about 11.7V. Still the extruder cannot exceed 238-242degC. Strange, because I thought this was a standard 3D printer cardridge. Apparently, it is not aby Stephanel - Delta Machines
I use a rather thick cable which normally is used for lighting etc. The voltage at the power inlet of the RAMPS board is 13.5V as set in the power supply now. All screws are tight. That might be a reason. I feed the board with 5V through the USB port coming from my PC. The laptop is plugged in. Not sure if it provides sufficient power? I also did not find another way to power the 5V without PC.by Stephanel - Delta Machines
Damn, think I wrecked my RAMPS board. A heat sink fell off and hit the driver of the extruder. Now the extruder won't work anymore. I tried to put the extruder motor on the X axes, and it still works. Exchanged the motor driver, but that didn't help. Probably the board has blown a fuse or so... :-(by Stephanel - Delta Machines

I just measured the output on the extruder. For some reason, it only gives 10.64V. I already increased the power supply voltage to 12.6V. The mosfets now are cold (let them cool down), but apparently there is some kind of voltage drop in the RAMPS board?by Stephanel - Delta Machines
Thanks ! I have 2 fans (5V on hot end and for board) running on the RAMPS. Do I understand that I cannot increase the voltage if I have these attached? I now have 12.2V on the power supply.by Stephanel - Delta Machines
I must say that the Mosfets get extremely hot. The heatsinks are blistering...by Stephanel - Delta Machines
