@neutronken It will do it again and again that is why mine is apart.
1.) The wires from the bed need a strain relief otherwise the connectors on the board wiggle back and forth as the bed moves and arc and that melts the connector. etc. your mosfet is probably fine but the connector is shot - the only way to save it maybe is break the plastic out, clean up the studs and solder to it.
2.) You will have the same problem on the power input only it will take at least 2x as long. The problem is the Pulse runs at 12 V and has only a 15 Amps PSU (where the rambo website says use 16A minimum at 12 V. Plus you need heavier wires to the bed if you run it close to 100 and wires that are high flex silicon insulated and 14 gauge or less so they dont get hot plus it should run underneath it with a drag chain.
3.) You'd be better off to replace the PSU with a 24 V 15 A. or at least 24 V 10A but most are 360 watts or so. For that you will have to replace the heating cartridge and fan on the V6 and change the wiring on the bed.
4.) It is also suggested that there is cooling on the mosfets both the one for the bed and the Hotend IOW the case should have at least a 5010 fan or better blowing across the board to keep the heat down. Cause if you run the pulse like me (Bed 100 hotend 260-290) then some areas of the board will get quite hot.
So to make the Pulse a sound printer it needs at least a 24V PSU, 24V hotend, an electronics case with a fan, the wiring properly run to get rid of the "birds nest effect" And a different hotend mount preferably not done in Ryno that does not either cause a thermal runaway on the bed or the hotend when you run the printer hot as described above
I am also working on an enclosure for mine, and change the mount of the extruder and put the filament on top of the cage and change the hotend mount with one with a better fan.
So II think the only thing that might stay original is the extruder and the frame and the X/y/Z motors and mounts
@cdk Good luck even though hotend problems usually are wear and tare - doesn't take much to kill one. I got a pulse and its undergoing major surgery. IMO its a printer that is grossly overpriced and misrepresented. I Bought a 2 Chirons, upgraded them to all metal and such for less than I paid for the pulse. Did have some issues too but less than with the pulse. But then we had some problem with makerbots and ultimakers too. So if you 3DP you will be fixing printers - no matter what you spend. I know some people who have some funmat HT and markforged X3 and they need fixing too.
HTH
@cdk I have no in between layer code. I use the same start and end code in Prusa slicer as the default code in MC is. As the G code is not slicer dependent but machine specific. So you can copy and paste the Start and end code from MC that is the proper one done by Matterhackers for the the type of Pulse you have. Currently my Pulse is going through some major changers/upgrades in between other projects so my start and end codes are being messed with quite a bit and are a work in progress.
@mark8967 I have had the best experience with keeping it at 100% and increasing the layer height for the first layer and reducing the Z offset and with that achieve pretty much the same. Remember all the printer does is move the head and spit out filament at a given rate so increase the layer height for the first layer means more filament , decrease the Z offset brings the nozzle closer to the build plate so the filament gets forced / squished more into the build plate

If its on the bowden side. You can also use a zip tie of just the right size and pull the black thing up a bit.
@rjderama Glad you found a workaround. And with the filament feeding.... TPU is fiddly as it got about the consistency of a wet noodle. A lot in printing is still trial and error
Thanks for the insight. I figured it wasn't normal. I haven't tightened anything because I'm afraid I'm gonna mess things up. I think me being too careful has got me to the same spot!
I'll contact support to see what I can do
