One thing I would say A602 printer, the heated bed should be plain metal on top, with the writing underneath (unless they have changed the design) If I were you I would check the instructions to make sure it is the right way up. Daveby davy999 - General Mendel Topics
Any problems let me know and I will put them in a dropbox folder for you. Daveby davy999 - General
When you connect the printer does it show in device manager.with a com port number?by davy999 - General Mendel Topics
I have sourced 2 of the above printers, they are Amazon Returns and with a much reduced price. Failures are unknown but all the ones I have seen / assembled were due to operator error and the units themselves work fine. The seller will replace any possible missing parts, but will not provide tech support, however I have been helping them out with tech support for several customers and I am williby davy999 - For Sale
Glad you guys are having success. I am a completely noob with these things but I am very happy to help in any way I can. Daveby davy999 - General
Are you certain you connected both ribbons at the back correctly, the right way around and fully home?by davy999 - General Mendel Topics
I have an A602 and there is a folder on the SD card marked STL files, they are all of the parts you need. Let me know which part you require and I can send the appropriate STL file to you. Daveby davy999 - General Mendel Topics
If you are using Repetier to control the printer, you need to look in the printer settings of Repetier, that is where you set the baud rate of the printer to 115200. Daveby davy999 - General Mendel Topics
Good to see that you have progressed further. I have yet to trial ABS so will be very interested in your results. Daveby davy999 - General
My i3 connects at baud rate 115200 Maybe try that?by davy999 - Reprappers
When you connected up, did you set the baud rate correctly to 115200 and loaded in the drivers as per the instructions? You also have to see what COM Port the USB has been assigned and put that into the software? Daveby davy999 - General Mendel Topics
How did you get on with this problem? Did you find a solution? Looks to me like the first layer and second layer are not stuck together, maybe reduce the first layer height and it might squash the 2 layers together more. Daveby davy999 - General Mendel Topics
The A600 uses a spring to apply tension between the roller bearing and the motor shaft. The build instructions just show a spring being inserted into the assembly, but there are 2 lengths of spring supplied, you have to ensure you use the longer spring that provides more pressure on the filament and should lead to a dependable flow of extruded material.

Hi Julo Is the baud rate setting correct? Details should be in the instructions. Daveby davy999 - General Mendel Topics
The problem was Slic3r software had no start or finish defaults in the gcode. Using Cora to process solved the problem as it forces the printer to go to XYZ datums first, simple really! Daveby davy999 - Reprappers
Hi Darko I am glad you have made progress. Is that PLA you are using? what temperature are you heating it ? I have bed 55, nozzle 210 Daveby davy999 - General
Hi Darko I am also a newbie, I have only had my printer for 2 weeks!! :-) You load the .stl file into Cura, then save it as a G-code file. Open Repetiere software and connect to the printer (do not go into the Slic3r part of the software) Open the Gcode file you outputted from Cura and (if all settings are done) hit Run and it should hopefully begin printing correctly. Cura is a program that tby davy999 - General
Hi Darko I started with Cura, and it seems the most simple one to use as it worked for me first time. It will be interesting to see your gcode file as I suspect it is missing some of the initiation parameters. Daveby davy999 - General
Hi Darac What software are you using to create the Gcode file? It sounds like you have not got the start and finish parameters set in the gcode. (something like G28 X0 Y0 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops Also, have you adjusted the table height in line with the instructions using the 4 spring adjusters in the corners? You need to just be able to slide a single sheby davy999 - General
Hi Again Nigel The mesh should be an infill layer, but if your top and bottom layers are mesh like then you will need to increase the top and bottom layer thicknesses so that they completely mask out any infill underneath. Do you have a small object that you can 100% fill and see how that appears? I can send you a processed Gcode file that is ready to go and just needs loading into Repetier andby davy999 - General
Do you have any pictures of the parts so that we can see the problems you are having?by davy999 - General
Hi Nigel The quality is very good, I have attached a file showing a small pot and to me the finish is more than acceptable. I am curious as to why you are using Slic3r for the processing as in my instructions it recommends Cura for slicing until you get confident with the printer. I find Cura much more straightforward to use for the beginner, I am sure slic3r has its uses but Cura seemed to be sby davy999 - General
hi Nigel I have the same printer, if it helps I can send you the settings from my printer and see if they work for you. Daveby davy999 - General
Hi All I recently purchased and assembled the above 3d printer and it seems to perform fine, except that the Z axis seems to be erratic. I have set the table bed height using a sheet of A4 paper and all seems ok except when I try to print a model. The three axis go to the datum switches but when it goes to print the starting height of the Z axis is random, sometimes it starts a few mm above theby davy999 - Reprappers
