![]() I would start by using the values from your config file provided by the printer manufacturer in your slicer. Reprap and Marlin are very similar, but some of the commands are slightly different and use different units (e.g speed & jerk are in mm/min in Reprap but mm/s in Marlin). Regarding the firmware flavour, you should definitely set it to Reprap. On an 800mm tall print like yours can do, this can make a world of difference on print times! In the Slicer you can usually set different limits for different move types, so you can have fast, high acceleration moves forthe infil where ringing/quality is less important, but slower and more controlled moves on the external perimeters where quality is paramount. things that will mean it won't skip steps, break itself etc), then set more detailed/controlled limits using your slicer. General advice is to set sensible limits for the machine in your config file (i.e. For this you can play with speed, acceleration, and jerk, and you can adjust them in your printer config, and/or in your slicer. In general it comes to trying to push a heavy print head round a corner too quickly, meaning the flex in the system bounces a bit and causes the artefacts you're seeing.Īs well as changing the belt tension, you might want to double check all the joints/bolts/connections on the gantries are tightened - In the past I have found a screw loosened in the printhead which gave me some ringing.Īfter that you're mostly onto tuning the printer to try and slow it down round the corners. I'm guessing you have already read up on what ringing is and things you can do to change/improve it. I'm absolutely new to all of this, so I would greatly appreciate any help and advice on this Hello and welcome to the Duet world! What GCode flavor should I use in Cura? What jerk/accel values should I set? Will that even make any difference, since the config already has some values? I also noticed that the printing time is always significantly longer than what the slicer estimates. M84 S60 X Y E0 Set idle timeout - one minute M204 P500 T1000 Set print and travel accelerations (mm/s^2) M566 X240 Y360 Z30.00 E120.00 P1 Set maximum instantaneous speed changes (mm/min) The printer has a config file that has some max values already set: M350 X16 Y16 Z16 E16 I1 Configure microstepping with interpolation The second thing are the jerk/accel values. Which is the first thing that confused me, since this is a RepRap printer? The manufacturer has a short tutorial on how to setup the printer in Cura, but that tutorial doesn't say, that I should change the GCode flavor from the default Marlin to RepRap. I read that I could try enabling the jerk/acceleration control in the Cura slicer but I'm lost on how to set the values. ![]() I tried tightening the belts, I tried loosening them, nothing made a real difference. ![]() I'm having issues with ringing/ghosting in my test prints.
