As far as knowing about your changes you should now be able to crank up your temp with out it stopping because of max temp error. Assuming you remembered to make the max temp change to 350. Or did you just change the thermistor type?

no I changed the max temp to 350, and used the thermistor that came with the E3D

Re: x axis homing to left?

So just run your temp up to like 300 (check the E3D Documentation) it is part of the install instructions for the E3D anyway and that step shouldn't be skipped.
If it runs up past 230 then you are ready to go.

Re: x axis homing to left?

ok looked over that everything is good to go.

question, so to change the temp for the hotend where do I go?
I tried changing it in RH under config under slic3r, then go to filament settings, but it jumps back to the old setting of 195* I want 200* why is not staying and saving at 200*?

Re: x axis homing to left?

A few different places...
The start code is probably what is getting you though. The line just above the highlighted one and one near the bottom that isn't in that screenshot.

Re: x axis homing to left?

not sure this is the start code I have.

oh and how tight/close should my nozzle be to the bed? I apparently don't have it close enough

Oh... you probably want to run about 230 to start with.

Re: x axis homing to left?

oh yeah and for some unknow reason, my z axis is pulling away from the bed a hair on start up.
and yes my z offset is at 0, so im kinda confused on whats telling it to do that.

here is the start g code from the menu you are at showing me yours.
looks like im missing some stuff.

Re: x axis homing to left?

So it is right there for the Z movement...
Just remove the lift nozzle line or just replace it all with this start code (see below). Make sure you change it in printer settings in R-H and in filament settings in Slic3r.

G21; set mm units
G28 ;home all axis
G90; set absolute coordinates
G92 E0; reset extruder distance
M104 S245; set extruder temp and start heating
G1 Z5 F300 ;move platform down 5mm
G1 X193 Y187 F3000 ; move to back right corner
M109 S245; wait for extruder temp to be reached
G1 Z[first_layer_height] F200 ;move platform close to nozzle
G1 E7; extrude anchor
G1 F3000; center print head
G92 E0; reset extrusion distance

Re: x axis homing to left?

will do thankyou again for this help.

some time I feel dumb.

why do I want this line of code?
G1 Z[first_layer_height] F200 ;move platform close to nozzle

Re: x axis homing to left?

You can put a ; in front of the lines you don't want. That lines creates an anchor so you don't have to clean the ooze from your nozzle right before it prints.

Oh... There is no reason to feel dumb. We have all been there at one point in our lives and 3D printing has a steep learning curve.

Re: x axis homing to left?

so for .3mm prints it should look like this
G1 Z.35 F200 ;move platform close to nozzle

Re: x axis homing to left?

Sorry about that no that 5mm should be left alone
I was thinking this one.. G1 E7; extrude anchor
Just copy the one I posted exactly like it is. You will like it and none of it relates to .3 .2 or .1 layer heights.

Re: x axis homing to left?

G1 Z[first_layer_height] F200 ;move platform close to nozzle

so the way this is written this [first_layer_height] is actually telling the printer something? its not a comment?

Re: x axis homing to left?

Yep. I haven't steered you wrong yet. Just give it a go if you don't like it you can always change it back. I'm checking out for the night so good luck.

Re: x axis homing to left?

so I fail.
don't know why this is happening.

this is ridiculous. it should not be having any problems.
bah.

here are pics

I know, I know the fix to this problem, im just brain farting.
I don't have a clog already do I?
hotend E3D, mk5 extruder.
hotend temp is 230
bed is 100

this is the start of my box test print.

Re: x axis homing to left?

In words what do you think is happening? You are over extruding at least on that first layer. But other than that what isn't it doing? On my phone so hard to tell from picture.

Re: x axis homing to left?

no that's the thing its doing is laying a bead of fat skinny fat skinny, very consistent.
how do I remedy over extrusion?

Re: x axis homing to left?

So it is wavy? that is most likely caused by the stepper driver. Some of that can be adjusted out (VREF's) via the small Pots on the board. There is one for each motor and you can adjust them by ear. Draw a line on the drive gear so you can see it. Then in R-H in the manual tab set the extruder speed to 50 mm/s and set it to extrude 100 mm's. (hot end at temp). This should give you 2 minutes to make the adjustment.
Use a small screw driver that fits the pot on the appropriate driver and adjust it until it sounds a smooth as possible. The line on the drive gear will help you visualize the pulse of the motor. The goal is to eliminate (as much as possible) the pulse of the 1/16 micro step. The E3D is much more precise than the stock hot end so this pulse causes what we call moire.
Get through this step and then I'll help you with the calibration for extrusion.

I did the calibration of the extrustion motor already. for the flow rate. is that bad that I did that already?

so this wavy problem is normal for having just installed the E3D?

It isn't a bad thing but adjusting the VREF can throw that calibration off a bit. Worst case you have to redo it but at least you'll have to recheck it. The wavy problem your having is a combination of things but in a nut shell you are over extruding on the first layer for the given Z-height adjustment. The work around would be to increase your Z-screw at the price of good adhesion to the bed. The correct way would be to dial in that Vref and then calibrate your steps/mm. Then adjust the extrusion multiplier and lastly tweak that first layer extrusion width till it's nice and flat.
