Hi, It appears the issue was indeed solved by checking all thermistor connections. Looks like one of em was loose.by DaSt - Printing
Hi there, I know it has been quite a while but after this issue I quit printing for quite some time and had some other issue of my own. I plugged the printer back recently and began with that very same issue. In fact when i could have a correct first layer I noticed many layers in any print would be very weak. I tried recalibrating the e-steps but it just looked like nothing there would help eby DaSt - Prusa i3 and variants
Another print failed the same way. Deconnecting and reconnecting the TFT28 won't allow me to send any command to the printer. I replugged the serial screen and when launching a print I have a thermal error quite quickly. I think I just had a thermistor bad contact on motherboard side. Let's see if the print goes smoothly this time x)by DaSt - Printing
Hi, I'm printing using an anet A8 modified with ramps1.4 (Marlin 1.1.8), aluminium frame and a a few other upgrades. A few days ago I had to move the printer from a desk no another and as I was gently dropping the printer on the new desk I may have let go the left side (on which the motherboard is resting) from 10cm. Shame on me, I know, but hey it does happen. I've tried printing from S3D (usby DaSt - Printing
Hi there, Reading through forum I saw that S3D increases the flow whenever the first layer height is above 200%. When I use 300 to 600% i guess it may be normal to overextrude, then. What if I try to reduce the first layer height in S3D while compensating by increasing the distance between nozzle and bed via modifying the Z offset ? Thxby DaSt - Prusa i3 and variants
Hi there Quoteo_lampe Did you calibrate the e-steps? You might be lucky and the extruder current is set low enough to skip steps when it actually would overextrude. It shows only when 1st. layer is set very high. I tried before posting yesterday. Following the process I noticed that extruding 10mm does indeed use up 10mm of filament but extruding 100mm only uses like 40mm of filament o.0. I endeby DaSt - Prusa i3 and variants
Hi, I'm using a modified ANET A8 with RAMPS 1.4, Marlin 1.1.8 and a BLTouch sensor. Problem is the first layer is never really clean (seen from both up and down) even though the rest of the print is quite good. I mainly print at 0.16 and .08 but the issue is consistent no matter the layer height. 200°/50° temperatures, using S3D. Z offset has been setup several times (always finding the sameby DaSt - Prusa i3 and variants
Hi, Thanks for the input. What about putting the extruder motor inside the enclosure and what about the vibrations ? Thanksby DaSt - Prusa i3 and variants
Hi there, I would like to build an enclosure (with Ikea tables) for my Anet A8 printer but I have a few concerns: - Should I put the power supply outside the enclosure ? - Is it recommanded for direct drive setups since the motor will be confined in a more or less heated chamber ? - My printer is currently bolted to an heavy wood panel, sitting on a foam mat on a traditional desk. If I bolt theby DaSt - Prusa i3 and variants
QuoteMMcLure Make sure that none of the tabs on the RAMPS MOSFETs are touching each other. If they do when one MOSFET activated the touching MOSFET will also activate. I had this problem with almost exactly the same symptoms you're experiencing and I've seen at least two other people with the same problem - just bending the MOSFETs to ensure that they do not touch each other should solve this issby DaSt - Firmware - Marlin
Hi, With some more testing i can confirm that heating the bed if powering on the fan. Heating the hotend alone does not.by DaSt - Firmware - Marlin
I'm using Simplify3D just like i did before Marlin (didnt have that issue at the time) with 0% power for first layer and 40% power starting at layer 2. Thanksby DaSt - Firmware - Marlin
Hi there, I'm using a modified Anet A8 with auto leveling and a RAMP 1.4 board. Marlin 1.1.8. My part cooling fan is powering on at 100% by itself when heating begins, or sometimes when the bed reaches 50° or so... It goes on during the auto leveling process. It shuts down when the printing begins as I have a M107 command on my startup script, but then it get back to 100% during first layerby DaSt - Firmware - Marlin
