After a long hiatus I picked the printer up again. Lots of under extrusion. Using Gregs tips above, it was because the default firmware had the filament diameter set for 3mm on T1 and 1.75mm on T0. Changing T1 to 1.75mm made a big difference. Also the Esteps were set to 90 for E1 and 800 for E0, changing that has also helped.
Now to check the parameters and tweak and then try the laser engraver!!

Wow that's brilliant. Interesting about the speed settings. I'll give that a try and see what comes back. Tried to run a print this morning with the acceleration settings you had previously suggested and still had a massive layer shifting.

PS: Just to ask, is the official firmware uploaded by Selpic on their GDrive a Marlin variety does anyobody know (https://drive.google.com/drive/u/0/folders/1bycAdD8w0i8erV1dOLaPR5-pJKBIHhBt). Also, is it worth using cur 4.6 rather than upgrading to the 4.9
I have the Star a and an Ender, Ender is no problem, but the Star is causing all sorts of grief. I've hesitated using Foos Marlin as i also have the laser engraver and the way its going, it may be the only thing that actually works on this printer

thank you i'll give that try. Worst bit is that the Rocket prints fine but anything out of cura messes up

Will try that thank you

Hello all, any advice would be great
I have the Star-A printer. Upgraded to the official firmware posted in May by Foobar. Originally I had Cura setup as RepRap as per the instructions set by the company. Prints weren't perfect but ok. After the first firmware update, my filament started blobbing (coming out thick and thin, not consistent, gear slipping as it was pushing out too hard. Next firmware update in May, updated, looked at the new instruction posted above and downloaded the cura profile. Instructions now state Marlin. Made sure Cura matched. Went to do a print and...(see the pink prints in pic 1)
Ive seen layer shift, but this is a whole new level. the left was take 1 with jerk and acceleration control. Right hand one shifted after about 1mm and started printing about 20mm off where it should. Both the RepRep and Marlin have extreme layer shifting. I'm confused as to what the cause could be, I've tightened all the belts and screws. the two Calicats that completed were printed out on the first firmware. Ever since then its been downhill and i cant figure out why.
Support has stopped relying to any of my emails. I'm hesitant to install the custom Marlin fork that Foobar has kindly compiled as i also have a laser engraver (not yet used but want to). My start G-code is:
;Sliced at: {day} {date} {time}
;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}
;Print time: {print_time}
;Filament used: {filament_amount}m {filament_weight}g
;Filament cost: {filament_cost}
M140 S{material_bed_temperature_layer_0} ;Set bed temperature
M104 S{material_print_temperature_layer_0} ;Set hotend temperature
M190 S{material_bed_temperature_layer_0} ;Wait for bed temperature
M109 S{material_print_temperature_layer_0} ;Wait for hotend temperature
;Next 3 values were set in the provided gcode profiles from selpic
G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28 X0 Y0 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops
G1 Z15.0 F{travel_speed} ;move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
G1 F{travel_speed}
;Put printing message on LCD screen

PS: It is noisy. the fan is offset to the holes cut out and are excluded somewhat by the internal wires. Stepper motors are noisy, but not as much as the fan
