Re: Simplify3D settings for MK3


You can also just copy the Slic3r way of doing it:

M104 S[extruder0_temperature] T0 ; this will take the layer 1 temperature for extruder 0
M140 S[bed1_temperature] ; this will take the layer 1 temperature for bed 0
M190 S[bed1_temperature] ; wait for bed temp
M109 S[extruder0_temperature] T0 ; wait for extruder temp

P

I don't believe that'll work with Simplify3D. The codes that actually set the temp aren't in the scripts tab. They're generated by S3D based on all the checkboxes and whatnot on the temp tab.

I copied that out of the "Starting Scripts" tab in my Simply3D profile, seems to work fine. I believe the [bed1_temperature] is substituted with the temperatures from the temp tab when the script is run.

EDIT: Indeed; it's not well documented by Simplfy3D for some bizarre reason but there's reference to it on their forum here https://forum.simplify3d.com/viewtopic.php?f=8&t=1959

If you're not a fan of the fact that Simplify3D heats up the bed/extruder, th[e]n runs your starting-script, you can customize this, by using the commands below. If you have the commands for [bed#_temperature] or [extruder#_temperature] in your starting G-Code script, the software won't add in heating commands, it will just run off of the commands in your starting script.

[fan_speed_percentage]
[fan_speed_pwm] - for example, M106 S[fan_speed_pwm]
[extruder0_temperature] - for example, M104 S[extruder0_temperature] T0; this will take the layer 1 temperature for extruder 0
[extruder1_temperature]
...
[bed0_temperature] - for example, M140 S[bed0_temperature] T0; this will take the layer 1 temperature for bed 0
[bed1_temperature]
...

Re: Simplify3D settings for MK3

I gave the above a try and found it wasn't heating the bed. I believe the correct code is:


M104 S[extruder0_temperature] T0 ; this will take the layer 1 temperature for extruder 0
M140 S[bed0_temperature] ; this will take the layer 1 temperature for bed 0
M190 S[bed0_temperature] ; wait for bed temp
M109 S[extruder0_temperature] T0 ; wait for extruder temp

Note the change to bed0 instead of bed1. Seems to work now.

Re: Simplify3D settings for MK3

I assume the reason why the bed gets heated up first is that it takes much longer time to heat the bed, and the nozzle gets compared to that much faster to its dedicated temperature. On the other hand the bed has some time to settle during the one minute the nozzle needs to be ready. If you have a temperature sensitive filament loaded it could lead to problems if it sits in the hot nozzle for idle until the bed is heated up (carbonizing, clogging, etc.). If you have to change the filament you would preheat the system anyways. I'm also not a fan of hot and totally liquefied material dropping onto the PEI surface, and getting oozed onto the surface during auto leveling.

In my opinion the one extra minute is worth it compared to a several hours print.

I'm getting results with SF3D that please me pretty much. I'm using the latest SF3D out of the box profile for the MK3, the only things i changed were reducing the wipe distance to half of the nozzle diameter, raised the coast a bit (still layer start/end points are not perfect yet) plus in the ooze control behaviour:

Only retract when crossing open spacec: false
Force retraction between layers: true
Min travel for retraction: 3mm
Retraction during wipe: false
only wipe extruder... false

Extrusion multiplier is set to 1,00, Filaments Diameter measured out at 1,735

the attached pics are models printed in 0,15mm layers, speeds as the profile suggested in 80mm/s, outermost perimeters: 50% (100mm/s work perfectly fine too). The Body of the AMAO was printed in one piece, and every part is perfectly moveable.

Re: Simplify3D settings for MK3

Well, Im happy to announce that I´m back.

Had to take a break from 3D printing since my printer broke down and it took longer to fix it then expected.

(Extruder thermistor broke down, afterwards filament sensor broke)

Still, with replacement parts it works now and Im printing a masterspool for starters.

I still have to fiddle around with the settings, but I now have time and the printer again to get back to it 😉

So stay tuned for further tweaked S3D settings.

Re: Simplify3D settings for MK3

I printed a few small gears with .150mm layer height and had to readjust the live Z setting to get the 1st layer to lay down well again since I normally print with a .200mm layer height. Is this normal to need a Z height adjustment when changing layer thickness?

Well, you do have a height difference of 0.05mm from before.
But normally it should still adhere to the bed, maybe your bed level wasnt that good before either?
Such small difference shouldnt make a difference between perfect first layer and not sticking at all.

As long as the first layer sticks well after you changed it, everything is well isnt it?

I guess I was searching for an answer if the Z height would automatically change based on the preset layer calibration height. I would think the layer height could change and have the Z calibration follow suit.

Here is a 20mm Test Cube just printed. Inland PLA white. S3D slicer .200mm layers. Not happy with these results so far.

Thanks for the info.

Re: Simplify3D settings for MK3

I thought I saw from some of your earlier posts that you were having good prints now? Is this typical? It looks over extruded to me.

Re: Simplify3D settings for MK3

I have had some luck but still not satisfied when compared to others I have seen here. Yea it does look like it's a bit over extruded. Currently it is set to an Extrusion Multiplier of 1.0 and I'm running 205 degrees 1st layer, no fan then 200 degrees 100 % fan. I'l try another at .97 EM.

Update:
Second cube printed with EM set to .97 and it is a little bit better but the corners are still bulged and has horizontal lines on the sides and the 1st layer lines are now opening up with gaps. I will try EM set to .95 this time.

Update 2:
The third cube printed with EM set to .95 and didn't get much better. The corners are still bulged and the horizontal lines have very slightly reduced. I increased the 1st layer width to 130% and the height was set to 80%. The ringing has decreased a bit as well.

I thought these Prusa i3 MK printers were under extruders. Anyways that's enough for now. Good day to you all.

Update 3:
I plan to reduce the PLA temp down to 195' printing to see if that will eliminate any corner ooze. I have slowed down the speed a bit so lowering the temp five degrees more should still allow the filament to flow in the hot end at that speed.

Corner bulging is likely being caused by not having Linear Advance enabled, especially so if you have dropped acceleration or jerk down a little. It goes away completely when LA is enabled. It's coming back in two weeks according to the latest blog entry.

Re: Simplify3D settings for MK3

That was my guess as well. I have been printing using White Inland PLA and making setup changes in S3D to get the best results. Just recently I tried some Matter Hackers standard Lime Green PLA which I think has just been re-branded as MH Build Series PLA. Once I got the temps and speeds setup I printed a few items which to my surprise came out quite well on the surfaces of the 20mm test block and the Tree Frog that I sliced in S3D.

The Inland PLA has less stringing and I print it at 200'C after the 1st layer of 205'C. The MH PLA is same temps but fine hairs can occure in places but I just burn them off. I need to check the layer bond strength of both plastics. Just now printing with Black Inland PETG since its setup and the results are looking pretty good as well in both surface finish and dimensions.

Will continue printing but wanted to ask if anyone has had regrets using the Matter Hackers Build Series PLA.

Re: Simplify3D settings for MK3

Don't make the bontech gears to tight. Try to make the filament to slip by holding it, you should have the least tension where you lose steps but not letting the filament slip. This will help releasing some pressure from the extruder stepper and might give you a more constant flow. otherwise you deform the filament to much, the stepper becomes hotter, and its very filament dependent how well the extrusion works.

Additionally: Doublecheck the filament diameter. 1,735 seems to be a magic number for my printer, almost everything seems to be fine with it, but i'm using mainly one brand. I once had some alike problems, until i recognized the filament i was using had a diameter of 1,78 to 1,83. The larger the diameter, the more volumetric effect will occur. That could be one reason why most filaments tend to be slightly under 1,75mm...plus the effect that a to large diameter wouldn' fit through some systems 😉

Re: Simplify3D settings for MK3

I have tried the settings and I don't like them at all. They are to hard in the movement and produce bumps on flat surfaces from organic formed skulptures which are produced for example in meshmixer.
Maybe they are good for technical stuff..... I didn't try yet, but the FFF Settings for the Original Prusa I3 MK3 which come with the 4.0.1 Update behave alot smoother.

Re: Simplify3D settings for MK3

Newb S3D question: How often will they update the printing profile for the Mk3? Say linear advance comes back, would proper profile be created for that pretty quickly by S3D? I am new to the software, so far I am really like the supports and the print quality has been at least on par or better then Slic3r PE for me. Much appreciated.
