  • Repetier said: If filament goes up over heat break it is not working as supposed. Reasons are cooling of heatbreak not sufficient or filament temperature too high. Sometimes it is also granular stuff in filament blocking the nozzle so all goe…

  • Aaa, OK. thank you for this suggestion. I will try and report. Also, I will try to modify the cooling fan nozzle, to concentrate the air flow to smaller area immediately around printing head.
  • The bed definitions  in configuration.h: #define HAVE_HEATED_BED 0 #define HEATED_BED_MAX_TEMP 120 #define SKIP_M190_IF_WITHIN 3 #define HEATED_BED_SENSOR_TYPE 1 #define HEATED_BED_SENSOR_PIN TEMP_1_PIN #define HEATED_BED_HEATER_PIN HEATER_1_PIN #de…
  • In configuration.h I found the following value: #define PID_CONTROL_RANGE 20 My bed temperature is set to 98°C, and error happens at ~93°..  so it doesn't make sense to me.
  • I suspect fan is the culprit, it is switching ON despite being disabled in slicer (I thought I sorted it out bu didn't, apparently).I can see on tempo graph that bed temperature is dropping at the same time fan is switched ON.

  • It was actually like below, I posted changed value ("255") >Bed Heat Manager

  • It may also be that my room temperature dropped or was too low because I opened the window to ventilate (fumes from ABS)... Also bed heater capacity may be close to upper limit (it is very hard to reach above 100°C.. so I keep it at 98°). I will tr…
  • Thank you for your reply. I am using 1.0.3 f/w. I will update to latest and test.
  • Last printer head temp reported is 233.85° which seems to be OK (much deeper drop occurs when cooling fan is started. BTW, I sorted cooling issue). > 11:58:37.540 : T:233.85 /235 B:95.63 /98 B@:255 @:20
  • OK, here it is again.. after ~15 min of printing, same error, relevant part of log is below. There was nothing indicating this shown on graph. I did nothing, just restarted the job and it went through OK. Also, despite cooling disabled ( Slc3 over…
  • Thank you for quick reply and suggestion :-)Yes, originally I had the problem with sensor cable, I suspected connectors (header on RAMPS1.4 or sensor, so I  replaced sensor + cable  (and added connector at sensor so I can replace sensor again in cas…
  • Also, I disabled cooling in Slic3, but it did not have an effect, fan keeps switching ON on printer.. I did not notice this kind of behavior on previous version of Host...
  • Well, this is a problem...  I haven't seen such converter and I did search a lot.
  • Yes, I think I saw that scratching needle and spring loaded holder somewhere on web, I liked the idea, it is a good way to go from Gerber to isolated tracks on PCB. Originally I wanted to end up with HPGL code (I have two plotters lying around and d…
  • I used engraver (T-tech, http://www.t-techtools.com/store/) and didn't like the noise and dust... Data conversion is a problem... Yes, there is a lot of google results for converters but none that I know of is as good as old, Autotrax DOS utility (p…
  • I found this article about the issue... a bit complicated, still it may be the way to go. http://reprap.org/wiki/Plotting
  • OK, Thanks :-)

  • When I tried to print in manual and dry mode, the printer started to move but it wouln't extrude.. and heater was apparently switched OFF (it started to cool.. but according to host, it was heating). What am I doing wrong?
  • Would M111 help here?
  • Yes.. However, the problem persisted until I went to older version(0.91). It is OK now.
  • Yep... before I read your reply, I actually tried with version 0.91 and it started to behave OK (missing steps). Slower speed and lower acceleration sorted the problem... so I am still wandering about the bugs :-)
  • I have no idea, but I have the same problem (X, Y are belt driven, 80s/mm works fine) but z is wierd (2mm/rev ACME screw), it behaves just like 3DMistery reported. It is a bug in the firware.. affecting only Z-axis (it appears that parameters in Co…
