Hi Tony just emailed you.

Hi dc42 thanks for that, the board actually came direct from yourselves.

Hi dc42, i actually live in Scotland so humidity isn't really an issue. The ajax errors have always been there but its the number of times that i need to re-flash the firmware that is starting to really frustrate. I can do a print and everything is perfect then go to do another and have no access to the web interface.

Hi dc42, nothing is pressing against the erase or reset ports like i said i always put down the ajax errors and odd firmware resets down to the firmware but over the months and update after update nothing has ever improved, it just seems to get worse. And as an early purchaser number 62 i think i never expected things to be perfect, but some stability would have been nice, the 2 Duet 0.8.5 i have i haven't updated in a long long time but work fine ( well except one with a fan issue but its fine ).

HI dc42 sorry about this but i have never been able to get a stable wifi connection with the DuetWifi, i have always put it down to firmware and the hope the next version will fix the issues but now even with your latest beta releases of 1.19 its even worse. After now 7 months of ownership the board when working is fantastic the only problem is it never lasts more than a few days before i cant reconnect over wifi or the web interface drops out constantly through ajax errors. I honestly couldn't tell you how many times i have come to the machine after a couple of weeks turned it on opened the web interface and nothing to find again for the god knows how many time the port says bossac and not lpt1 and i have to re-flash the firmware. Today was the last straw after running perfectly for 9 hours over the past 2 days i switched the machine off after the print finished and everything cooled down, went to turn it on this morning and again as so many times before no connection to the web interface, hooked up my laptop and again in device manager bossac. Decided to try 1.19beta2 followed your guide and all is well for 2 mins and never managed to got connected again. I know this isn't exactly a commercial board and is always under development but it should at least work more than 15% of the time. I have now come to the conclusion that i cant trust this board for any work i need to do but hope that you can get a handle on all these issues in the future. Because honestly when it works its great just not reliable.

No problem, its looking good. The firmware can be found at http://support.zortrax.com/downloads/firmware/?printers=m200 al you need is the serial number of your machine.

Think i will still stick with your original ones for any future purchases. Was just interested if you had seen them.

not exactly on the same subject but wondered if @dc42 you had seen these before Aus3d mini ir z probe? Just came across them while i was looking for something else.

Thanks dc, pots are adjusted to min sensitivity setting. I use a larger magnet than the tiny ones supplied. All cables i use are lapp LiCy. Cant do much about the planet i am on but they seem to be ok

Oh forget to say, when i saw your pictures it didn't look like there was a ground connection from your power supply to the chassis probably would be a good idea since its a metal cased printer.

Yep those were the dimensions used for the ultimaker bed, so use your Zortrax dimensions.

Sorry for your 12mm lead screw i dont know what thread pitch Zortrax are using.

Do you have a serial number for the printer because you could always download the latest firmware from their site. Then you can get all the original values from the actual firmware as starting point.

For your limit switches it will probably be

X axis homes to max
Y axis homes to min
Z axis homes to max

For me its not really the precision that matters as much as the reliability, being non-contact there is nothing to wear out so reliability increases.

Go to Zortrax and get the specs for your machine e.g stepper motor sizes thermistor types etc… , its basically an ultimaker clone so for basic parameters

X axis homes to min
Y axis homes to max
Z axis homes to max

X axis steps per mm 160 ; 1.8° steppers 16x micro stepping GT2 belts 20T Pulleys
Y axis steps per mm 160 ; 1.8° steppers 16x micro stepping GT2 belts 20T Pulleys
Z axis steps per mm 800 ; 1.8° steppers 16x micro stepping TR8 Lead Screw

or

X axis steps per mm 320 ; 0.9° steppers 16x micro stepping GT2 belts 20T Pulleys
Y axis steps per mm 320 ; 0.9° steppers 16x micro stepping GT2 belts 20T Pulleys
Z axis steps per mm 1600 ; 0.9° steppers 16x micro stepping TR8 Lead Screw

normally xy are 0.9° degree and z is 1.8°

so..

X axis steps per mm 320 ; 0.9° steppers 16x micro stepping GT2 belts 20T Pulleys
Y axis steps per mm 320 ; 0.9° steppers 16x micro stepping GT2 belts 20T Pulleys
Z axis steps per mm 800 ; 1.8° steppers 16x micro stepping TR8 Lead Screw

You need to check your stepper motor specs to be sure.

X axis max speed 18000 # mm/min
Y axis_max speed 18000 # mm/min
Z axis max speed 4800 # mm/min

X max travel 213 # max travel in mm for alpha/X axis when homing
Y max travel 179 # max travel in mm for beta/Y axis when homing
Z max travel 195.8 # max travel in mm for gamma/Z axis when homing

X axis current 1.3a ; 1300ma
Y axis current 1.3a ; 1300ma
Z axis current 1.0a ; 1000ma

E current 0.8 or 1.0a ; 800ma or 1000ma
E steps per mm 800 # Steps per mm for extruder stepper
E default feed rate 2700 # Default rate ( mm/minute ) for moves where only the extruder moves
E acceleration 1000 # Acceleration for the stepper motor, as of 0.6, arbitrary ratio
E max speed 45 # mm/s
E retract_length 5 # retract length in mm
E retract feedrate 45 # retract feedrate in mm/sec
E retract zlift length 0.15 # zlift on retract in mm, 0 disables

These are just sort of basic settings for an ultimaker clone, they will need to be tweeked for your Zortrax. But they might give you a starting point or just confuse you more

The two machines i use with the E3D titans are both deltas with bowdens. Not that it should matter i wouldn't have thought.

Normally an extrusion multiplier of 0.92 or thereabouts is for PLA and 1.0 is for ABS. Materials like colorfab xt are normally higher 1.05 or so. But to be fair it depends on the brand of filament more than anything else.

@ mjhall29 they are the same as the reprap.me ones just more expensive. They are available on aliexpress as well for alot less.

Have you seen these Hall Endstops http://www.reprap.me/hall-e-endstop.html ?

I use them on 2 machines and they work perfectly.

Forgot you can actually just about make them out in the pictures of my latest delta on this forum https://www.duet3d.com/forum/thread.php?id=357

I also have a couple of titans and run them at the suggested 419 steps per mm on two different machines both running 1.75mm filament with no issues at all. Both my titans have bog standard 1.8° 1.68A Nema 17s.

I also run E3d V6 hotends with 0.4mm Nozzles and use simplify 3d with a 0.4mm fixed extrusion width and an extrusion multiplier of 1.

@DjDemonD 290 seems extremely low.

I don't have mixing hotends though so cant comment on that.

Have you tried setting the extruders only to non-interpolated microstepping and trying again? it shouldn't make a difference but you never know.

you have

M350 X16 Y16 Z16 E16:16 I01 ; Set microstepping mode

Should it not be

M350 X16 Y16 Z16 E16:16 I1 ; Set microstepping mode

or

M350 X16 Y16 Z16 E16:16 I0 ; Set microstepping mode

Depending on whether or not you are using interpolation or not?

Also your X and Y axis steps per millimetre are the same but your motor currents are different? are you using different motors?

Eventually have found a chance to put my finished build up with the new DuetWifi, Controller is working beautifully so far without a hiccup.

Based on the Igus Hexagon V2 but shorter and fatter with linear rails and seemecnc injection molded arms. Build this one for simplicity and reliability and so far doesn't disappoint.

Actually in a home situation and considering its a topic about safety i would have thought the print would be of a secondary concern considering the whole principle of a 3d printer is you can print it as many times as you want. I would have thought personal safety the safety of your home and then the protection of the machine would have been the primary concerns.
