Now it's the long process of trying to tune the prints and improve my bed adhesion.
At the moment I the bed is probed in 5 places when printing, how would I convert to mesh bed compensation?
I'm genuinely surprised at how quiet it is! Do you have a donate link on thingiverse or a paypal account? I wasn't kidding when I said I'd be willing to pay and I do insist.
We're printing!!
I can already tell it's not a good print, but the fact it's printing is a massive step!
I'm using the recommended e steps for the titan extruder at the moment, but I'll measure this myself properly tomorrow morning.
I recalibrated the z offset and it came out at 0.995 three times in a row, where as beforehand it varied between 0.2 and 0.5.
I think the BlTouch was too high to work properly as you suggested.
Just changed some settings with the e3D and have ran a M303 to autotune and have set a M307 command in the config file.
I was having issues with adhesion earlier that I didn't used to have using Marlin.
I'm trying another print now with the new thermistor/PID settings.
Otherwise, it may be the Z offset that is off.
Hi, apologies I've been away a few days and had to collect the spare z nut holders (literally the other end of the country!!)
I've now repaired what became damaged.
I measured the BlTouch as suggested, to my surprise it was about 10mm higher than the nozzle, this was surprising as the whole carriage design is based around having this sensor and it's a genuine item!
I've now placed two washers between the BlTouch and the mount, this should bring it within the roughly 8mm.
This is the result of my mesh compensation now:
I'm using a genuine E3D V6 and having done a search of the forums, I have found this:
https://forum.duet3d.com/topic/2501/e3d-v6-thermistor-settings/7
Am I right in saying that I need to use?:
M305 P1 T100000 B4725 C7.06e-8 R4700 ; Set thermistor + ADC parameters for heater 1
I changed the M556, M203 and M201 as suggested and set the printer to Home All in preparation to re do the Z Probe calibration.
Unfortunately, the nozzle crashed into the bed again and this time I didn't catch it time, it's now damaged the mounts which hold the z axis nut on the left side.
I have replacements which I'll fit, then I'll re-attempt to Home All again.
This whole printer seems like 2 steps forward 1 step back!
I'll update when I replace the mounts.
Could me setting in the G31 Z value to 0 (As per the calibration instruction) have anything to do with it?

@latexcupcake Thank you for this, I've adjusted all my speeds to match yours. The Z axis is much quieter now.
Which extruder do you use, if I use a geared titan will I need to have a different speed?
This is the gcode I currently have ready to print.
This is the result of "Perform automatic bed compensation/calibration (G32)"
This is the result of "Perform automatic mesh compensation (G29)"
I'm not sure what's happening with the rear left of my bed in this case...
I can confirm that Home X, Home Y, Home Z and Home All works from the "Head Movement" menu.
I have aligned the x axis with the chassis of the frame (as advised by the creator of the printer) using two identical portable USB batteries.
I went to video the start of a print and the following happened.
It completed the G28 and then completed the G32, it then did it's priming streak in the gcode. As it was doing this and as it moved to start it's first layer the extruder was clicking. I thought this was either temperature too low or nozzle too close to the bed.
I'm printing in PETG and having used this filament before I set initially set it to 230 degrees and tried to extrude, but got clicking.
So I now have it set at 245 degrees and it'll extrude (although it seems to cool very quickly so it may still not be hot enough.
I tried to print again and there was more clicking, knowing that the temperature was able to extrude now, I decided to check the z offset.
In marlin, I used to use M851 Z-. and trial and error until I had it tuned in, but because I still don't know how to do this on reprapfirmware, I decided to edit it in the slicer. I experimented until I found that 0.5 to 0.6 wouldn't click and would extrude.
When I went to print again, the printer successfully completed G28 and the four corners of G32, but when it went to probe the centre of the bed, it crashed into it again.
This is a genuine BLTouch so it should be ok, could it be it that's at fault?
I'm currently uploading a video to One Drive, you'll see that the head crashes into the bed, the BLTouch starts flashing and then it continues to print with the nozzle too close to the bed.
The video is here:

Apologies for the size, as you can see on the G28 and the four corners of the G32 the BLTouch works as intended.
Then either the nozzle crashes into the bed and just keeps crashing, or, as shown in the video it will crash into the bed, the BLTouch will start flashing and then the print will continue with the nozzle too close to the bed.
Done, still getting a nozzle crash when trying to print the calibration cube unfortunately.
I just want to say how grateful I am for your help.
Now when I try to print, it home all fine the first time, then goes to home all again and just crashes into the bed.
That's done, should I go ahead and try and print?
After a reboot Home all is now working.
I can confirm that M401 deploys the prove and M402 retracts it.
I'm not sure why it's set to -0.25 I think this was me in the early stages of trying to figure this out using it like the M851 command in marlin.
I've set it to 0.
I used the g30 command the deploys the probe and when I stop it with my finger it does stop.
The Home all command still doesn't work though, back to crashing into the bed.
I've added the G29 S1 to the bed.g file.
My firmware version is 1.21 (2018-03-21).
My S3D starting script for gcode is:
T0
M104 S[extruder0_temperature]
M140 S[bed0_temperature]
M116 H0
;M104 S[extruder0_temperature]
G28
;G32
G1 X0 Y20 Z0.2 F3000 ; get ready to prime
G92 E0 ; reset extrusion distance
G1 X100 E20 F600 ; prime nozzle
My current config with the suggested alterations.
The G28 command no longer works either, it just crashes the nozzle into the bed! Can't catch a break! 
I've made the suggested changes and I've calibrated the z offset, but when I go to print the nozzle just crashes into the bed until I hit emergency stop. Is it an issue with the starting script?
Thank you for the reply.
The printer itself is an AM8-BLV (https://www.thingiverse.com/thing:2567757).
It has a 220x220 heated bed and is using a BlTouch as it's Z-probe and a titan extruder.
This Is how I have things wired up, I followed the guide on the Duet Wiki to install the BlTouch https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe)
I have uploaded all of my config drives to OneDrive.

Any help would be much appreciated, I'm going mental with it.
I've bought a DuetWifi and for the last 3 months I've not been able to set it up with a AM8 I've built.
I used to have no problems when I used Marlin, I don't know, maybe it was something to do with how it was programmed or maybe it's because I learnt it first but now I've switched to the DuetWifi and the RepRapFirmware, it's just one thing doesn't work correctly after another and I can't seem to get my head around the documentation to figure it out.
I'm getting desperate.
Would somebody be able to offer me some one on one time online and I'll pay for your time.
Everything is wired up, I'd just need help configuring the board and getting it to work with my slicer.
If I can get it to the point where I can print a calibration cube, I'll be happy.
Where I am at the moment is that G28 works, G29 works and G32 works, but as soon as I try to print something, the nozzle just crashes into the bed. I think this is a combination of my slicer settings and my configuration files.
The Z travel is also way to fast and makes a stupidly loud noise.
Please don't take this as me complaining. From what I read the firmware and board are excellent, I just can't do it anymore, I've tried for so long to get it working that it's stopped being fun trying to figure it out, I'm borderline ready to sell up.
Any help would be much appreciated.
