Help! Print quality on my Malyan M200 is very poor lately. I had a clogged nozzle and bowden tube and was able to clean all the tubes. Then I also changed the nozzle itself and relevelled the printing bed. Now printing on 230°C and printing bed temp 70°C. But there seems to be not enough filament coming through. I think the printing bed might still be too close to the nozzle. Looking at the pics, what is your opinion/advise?
I have been printing with ABS for quite a while and thought I would pass on how I have learned.
- An enclosure is required. I made mine by making a box out of foam core. I added a door with a plexiglas window. The box covers the entire printer including the spool holder.
- Enable WiFi. This will let you to alter the heated bed temperature beyond what the dial will allow.
- Start with the heated bed temperature set for 80°C in the slicer then when the hot end starts to heat change the bed temperature to 90°C. The bed temperature doesn't make it to 90°C unless the print is over a half hour but it does help.
- Use a brim. I haven't tried a raft but that should work just as well.
- Print on glass with hair spray. (6 or 7 light coats or 3 heavy coats) Spray an additional coat after about 4 or 5 prints or if the print doesn't stick. in time the smooth coat will look rough and you will be tempted to wash it off and start over, but the ugly rough coat actually make the print stick even better, you just don't get the glassy look on the bottom of the print.
- Let the bed cool down before trying to removing the print. The print will usually come off with little effort when cooled down.
There you have it, my approach to successful printing with ABS.
I use filament from 3DXtech. The 3DXtech factory is in Michigan and close enough that I can drive there in about 30 minutes and their prices are only a few dollars more than what I was paying for Hatch Box through Amazon but I am happy to pay a little extra to support local businesses.
I wanted to do a name tag with a color change at a given layer.
To do this I used the Pause feature of the MP Select Mini but I knew there had to be a better way.
The plug-in for Cura doesn't work for the MP Select Mini so you have to do it yourself but it's easy.
I found out that the G-Code M600 does the same thing as pressing pause.
Here's the procedure.
First you will want Notepad2, I got it from Source Forge (https://sourceforge.net/projects/notepad2/)
Now load your STL file into Cura and save the G-Code.
Use the Layers view to find the layer where you want to change the filiment.
Load your G-Code into Notepad2
Use Find to search for the layer in the format of LAYER:n where n it the layer number you are looking for.
Enter a blank line before the ;LAYER:n
Save the G-Code.
That's it, just run your print, change your filament when it pauses then un-pause.
Here's a portion of the G-Code I edited and successfully printed. As you can see I made my filament change to take place at Layer 6
G0 F3600 X63.636 Y60.808
G1 F3300 X64.353 Y61.525 E217.03716
G1 F2400 E212.53716
G0 F3600 X72.011 Y66.700 Z1.500
I hope this helps anyone wanting a simple way to pause at a given layer.
OK this doesn't seem too active a group, but here goes.
I successfully printed the sample cat on the SD card supplied with the printer, using some fluoro yellow PLA.
However I tried again unsuccessfully with some black and some red PLA. The cat broke away from its raft while printing each time.
Anyone else had the same issue? Seems like a design flaw, that the connection to the raft is too fragile. Only gcode is supplied, so hard to edit.
hey i have my malyan M200 for not even a month and i really love that thing but at the moment im facing a problem. it seems like i have a clogg in my hotend. i already checkt my boden tube an my nozzel and the arent the problem so now my only guess is that it is the hotend. i cant pull the filimant out and of cours it wont go through.
