How Do I Calibrate My Titan Extruder and Test Print?
-
Just wanted to say thanks for a great write-up on the hot end issue. It's been this long since I've touched my printer because I had the whole Christmas break, back into work, then moved house, and frankly I just needed a break from the printer after calibrating for a whole year straight.
Every time I introduce a better part, it takes a bit of fiddling around and incurs a few new issues. Introducing the Duet was a big change, followed by a proper hot end. The funny thing about the clone was how well it worked in any condition, but it gave me very little know-how about the science you mentioned.
For now, I just need to go in for another calibration and see if I can get it working again. It's been heating the bed up to scorching temperatures on start up, with no input, which is a new issue. And I never fixed the issue with the printer sliding across the print early in the peace, then straightening up after 50 layers or so. There's no explanation how it can slip consistently at the beginning, and go straight up later. It's not a mechanical issue, so I'm stumped.

Have you already seen the release notes about adding "S2" to moves before an axis is homed?

Error since updating to Firmware 1.21:
G28
Error: G0/G1: insufficient axes homedYou're probably trying to move an axis before it's homed. Probably raising the Z axis.
From the 1.21 upgrade notes.
On Cartesian and CoreXY printers, normal G0 and G1 moves are no longer allowed before the corresponding axes have been homed. In particular, if your homex.g, homey.g and homeall.g files raise Z a little at the start and lower it at the end, you will need to add the S2 parameter to those G1 Z moves. Otherwise the G1 Z move will be refused unless Z has already been homed and the homing macro will be terminated.

I did catch the notes a few days ago, and have tried implementing it, but I'm formally an animator, not a programmer, so I have no idea precisely which file and what lines of code should include 'S2'.
I threw it in here (under Lift Z):

Additionally, since 1.21, it's heating my bed up on startup, over a 110degs-c, AND won't start the WiFi module, so I need to run M552 S1 in Pronterface with a USB connection every single restart.
1. WiFi module won't start when switched on.
2. Bed heats up with full power.
3. Can't Home All axis. -
Move the S2 to the end of the line:
G1 Z5 F6000 S2
…rather than:
S2 G1 Z5 F6000
-
G1 S2 Z5 F6000 will also work. The important thing is that the actual command (G1 in this case) comes first.
-
OK, updated homeall.g, homez.g and I get this error:
G28
Error: G0/G1: insufficient axes homedIt homes X and Y first, then stops. Does anyone have a copy of their homeall.g file so I can have a look at it and appropriate it for my printer? Is there anything else I need to update?

Please post your current homez.g and homeall.g files

Also, I just found out that my bed is moving backwards on the Y axis on start up, along with heating.
The only thing different about my printer before and when it was working is the 1.21 update.
1. WiFi module won't start when printer is switched on, and requires a third-party program to run M552 S1 to start.
2. Bed heats up with full power.
3. Bed moves backwards slowly on Y axis until Y stop on start up.
4. Can't Home All axis because the G-code is incomplete. -
This line in homeall.g:
G1 Z3 F200 ; Lower bed to avoid hotend dragging in bed.
needs the S2 parameter added.
Regarding the issues on startup, please post your config.g file.

If there's a vanilla config that comes with 1.21, maybe I should just start with that, then bring across some specific parameters for my printer.

is completely wrong. I suggest you delete it, restart the Duet, run bed heater tuning (M303 H0 Sxxx where xxx is the highest bed temperature you normally use), then run M500 to save the new M307 parameter to config-override.g. As you do not have a M501 command at the end of config.g to run config-override.g (which is a perfectly valid choice), you will then need to copy the M307 H0 line from config-override.g into config.g.

OK, ran through that process thanks. I copied the data across and it appears to be stable.

I'm unable to test the bed heater control, as I can't home the printer.
I've checked all the connections since moving, and everything is in place, however when I home the printer just rams X with the grantry and Y with the bed. The sensors are in place as well, so I'm guessing something isn't correct in the config again?

Geez this is complicated. I haven't changed anything, and they don't work. I don't know why I'm going over this again.
The end stop LEDs for X and Y are on, yet all the physical connections are good. I would think it's too much of a coincidence that both of them have failed at the same time, but I suppose there's a chance, and I'll have to order replacements which will take a while to arrive.
In the Machine Properties, it says X and Y are 'No' and Z is 'Yes' with:
; Endstops
M574 X1 Y1 Z1 S0 ; Define active low and unused microswitchesEven though X and Y are triggered, according to the LEDs on the board. Unless this means that faulty switches can't be triggered either way, and they're still showing up as not triggered, because they're 'un-trigger-able'. The Z is always triggered at the start, because it uses a BLTouch sensor, but doesn't show an LED light. The X and Y sensors both being faulty, for some reason, is the only explanation why this doesn't work.
