I just ran it through the relinearisation droplet now and despite its shape the droplet processed it and produced a new .quad, but I'm not going to bother seeing how well it was linearised for the same reason that I didn't try to relinearise it at the time. I did this as part of investigating which of the available K6 / P2 Piezography curves could be ported to my R1900. The curves from the recent K3 printers were fine. The ones from the 1430 and the 7000 were not. Thus there was no need to take it any further.
The relevance of this to Mike's situation is that if he has a measurement device then he may be able to relinearise the 1430 curves for the R280. But if he doesn't, then he's going to want a fairly good match as-is.
