This is becoming a running commentary, managed to get the cooling working! Only works during a lower layer height though?

Running the standard rambo if thats the right answer?


Still unable to get the fans running during bridging!

Managed to solve it with some fiddling, no idea what the problem was in the end though, just deleted pre sets and reconfigured a few times as well as restart both comp and printer

Hey guys, downloaded r-host and set everything up and still nothing with regards to it heating the extruder, target remains 0 on lcd screen, heats the bed though I am able to manually control the extruder before initiating a print, but once I initiate a print, there is no target for the extruder and ...

Have you set the start g-code to the same as the start g-code from MatterControl? I'm not sure if MatterControl is the same (it crashed 100% of the time on the machine I was using when I finished the printer, so I went to Repetier Host for it and haven't looked back), but Repetier-Host with default ...

I've been through all the settings and the config wizard and no matter what I seem to do, I cannot get the gcode from Slic3r to heat the extruder.

Help appreciated

Once again, than you all for the help, I'm moving to use Slic3r now in hope I can better control the bridging aspect

Right, Mattercontrol as slicer engine works fine, its only when I selected Slic3er as the enginer the x axis shoots across the leveling bed on at printing height

There doesn't seem to be

it's just when I print strangely

All the axis are performing correctly, just ran the tower calibration without any problems.

It homes properly

Started a Print again after adjusting z-height, this time print went straight down into glass, and kept driving before I managed to turn off by switch.

Went to adjust z height again, and now its at like 800.00mm , how can this be? No idea what is going on!

thanks all for the help, I'm slowly getting closer to understanding the software/hardware

Hi guys, My problems seem to be non-stop! Switched the machine on today to try out the Slic3er as a enginer after experiencing bridging problems, the bed heated and so did the hot end, it moved down to print and stopped mid way only for the x tower to continue going and keep going once it hit the ...

I see, will this enable the options further/different options?

Since you're using Sli3r, check the Advanced page on the Print Settings tab. The field you're looking for is called "Bridge flow ratio". Hop over to the Filament Settings tab and make sure that you've got "Enable auto cooling" checked and you've got valid values for the Min & Max fan speed. Check ...

Open the generated gcode and see what code it's passing to turn the fan on and off. Compare to the RepRapWiki documentation on gcodes for Repetier firmware. checked the code, I have the same code as displayed there, doesn't give me any further info to solve as to why the fans are not being ...

Is this matter control?

I've found that judicious use of a fan with ABS can greatly enhance printing quality... with the emphasis on 'judicious'. My ABS Marvins looked like poo until I printed a good fan duct and got my settings right. That said, to help bridging, try adjusting your bridge flow ratio. If the filament is ...

Koops, what parameter did JJ have you change?

g.

Ext.1 extruder cooler speed [0-255]

I'll take a look. Thanks!

Using a fan on ABS is a pretty effective way to ruin a part unless you know EXACTLY what you're doing. You might want to try increasing your bridging speed instead. g. I know how cooling effects abs, I'm trying to see if I can merely cool the first bridged abs because at the minute it's a pile of ...

Hello, I'm currently calibrating settings for achieving decent results via abs, I've reached the problem of bridging with such a material. I'm attempting to run the layer fan when the extruder bridges, and I have selected the settings in mattercontrol, however the fan will not activate during ...

You can add some insulating silicone wrap to the heater block to prevent the PEEK fan from impacting the hot end temperature. g. Problem solved now, spoke to JJ, he stated that the fan maye be "a turbo one" so I should edit the power of it in eeprom terminal, all done and hot end now achieves temp
