Good Day
Well after looking at all the brackets to hold the lead screws more secure, I noticed that the top brackets that come with the Flsun I3 to support the two Z axis stainless rods also have a 8mm counter sunk hole opposite each other that would support the lead screws if they were longer, so I bought two 8mm lead by 2mm pitch (same as factory) lead screws 400mm long and cut them to 368mm and voila they fit in the existing supports perpendicular to the stainless rods, complete X carriage is much more stable.
I have not checked yet but I should gain quite a bit of printing height as well, we will see how it go's.

Good Day
Well I have the Flsun I3 working pretty well now, the longer lead screws work fantastic, nice and solid and I was able to get about 250mm height for print area.
This is a great kit that is easy to upgrade, and I am a total newbie to the whole 3d printing thing, much more learning to do.

I disagree. The flsun3d i3 is not the same as the two printers you have provided links to.

Some similarities in that they all use 2020 extruded aluminium but the similarities seem to end there.

The shortcomings you mention are not present in my flsun3d i3 and my relationship with the seller was brilliant. I think you owe flsun3d an apology!

After that automated reply, I got ...nothing at all.

The image you have posted is radically different from my flsun3d i3. I don't think you are comparing apples with apples. My 2020 frame is incredibly rigid and displays no tendency to wobble. Are we talking about the same supplier? Mine came from flsun3d Printer Store, whom I found to be communicative and proactively helpful even though I did not have any issues with the product. Are you determined to besmirch a product which many here are finding reliable and very good value?

Yes, looking at the website it looks as though our reliable printer has been replaced by a new design. I have qualms about the top heavy nature of the tower with the Z motors on top. So I will agree that there is room for constructive criticism and maybe we will see an unemotional review posted here. In the meantime, LKCL, perhaps we can agree that not all flsun3d i3 printers have been created equal and care is needed in specifying models when making comparisons.

Yes, I think it is a pity they have altered a design which is working for us.

Just a hint of 'drift' using Slic3r, but much more like the originals when using Cura. I need to get to know Cura better.

I have printed all the parts for the X and Z carriages and mounts and the leadscrew brackets and I'm just waiting for the last stragglers of new hardware parts to come to hand. I also have a v6 extruder and I may use it as well when I do my mods. Not sure yet if I will convert the Y belt to horizontal orientation and have still to print the parts for that. This sure is a fun machine to tinker with!

hiya cheddy, i remember that nophead recommended the trick of putting several layers of cardboard (cutting up the box his kit arrived in.. ) in between the metal plate and the printbed. that stops airflow getting in underneath, and also acts as a heat-trap.

Hi Ikcl, thanks for your quick response. I don't think the print bed on my printer has two layers, just a single aluminum plate with wires attached underneath for the heater. It seems pretty rudimentary to me, with the heat being supplied by resistance in the wires and I'm wondering if I need to get a better heated bed. Or do you mean putting the padding between the plate and the BuildTak print surface?

hi folks, yes the sled, it's about 1in below the heated bed, on 4(?) spring-loaded screws for adjustment, that's the standard mendel layout at least. one layer of cork's not enough, you want enough (cardboard) underneath the cork to make sure that the cork is fully in contact with the printbed. cool-down time will be longer but you can do what nophead did with the mendel90 and add a side directed cooling fan (120mm). see mendel90 firmware for details if you want to set that up under control of gcode.
don't for god's sake just try blithely switching to 24v, you have to have either a printbed that can cope (re-soldering if it's a MK2 or MK3) or you need a minimum of a 500W PSU if you want to leave the printbed configured as-is. now you also need to make sure that the electronics (the crappy RAMPS-style stuff is unlikely to cope) is able to handle the current...
... but more than that you now need to change the heater cartridge to 24V (otherwise it will blow up - double the wattage will be supplied to it otherwise, that's now 50W to a heater cartridge: guaranteed burn-out and/or equipment fires), and replace all the fans with 24V ones, and.. and... and.. and...
overall cheddy i'd say try the cardboard, and if that doesn't work just don't bother, do what Ynotha did instead: get PETG and use that in place of ABS. i really like PETG, you can get it in translucent colours, it has a much higher glass point than PLA, has better structural rigidity than ABS, isn't as toxic (you will still need to vent the room), and doesn't need such ridiculously high printbed temperatures. there's nothing particularly fancy (that i know of) about it - nothing as bad as nylon (which needs to be placed in an oven @ some mad temperature for 6-8 hours because it absorbs like.... 15% of its volume in water or something mad, so when you heat it you get boiling water pockets in the heat chamber (!) and your print if you don't dry it out!)
anyway, lots of good reasons to try PETG over ABS.

Right! Of course! Put the insulation under the bed. What was I thinking? That would make a difference. I will give that a try.
Quote
How do you fix the padding to the bottom of the bed?
Quote
Do you use longer corner screws and put the leveling springs under the padding, with a rigid under-plate?
Quote
Got a spool of PETG filament on order. I'm keen to see how it works after all the recommendations.
Thanks for all the advice.
