I am about to purchase a 200W MOPA laser engraver with a JPT laser source, that being said however, there seems to be 4 different variants according to JPT’s charts.
There is the E2, E3 and either the L or the M variant.
The only difference I could find between the L and the M is the fact the L model has a slight higher pulse energy at 2mJ vs 1.5 for the M variant and has a shorter fiber length at 3 m vs the 5 m of the M model.
Seems like the E3 is the successor of the E2 since the specs are the same and the only difference is the weight and enclosure size being smaller on the E3.
I will use the laser engraver for the following in order of priority: laser cutting of metal sheets, laser marking, color marking and deep engraving.
That being said, which of the 4 variants would be best suited for my needs? Should I even consider the E2 if the E3 is out?
If not, then my choice becomes YDFLP-E3-200-M7-L-R or YDFLP-E3-200-M7-M-R.
To further complicate things, there is also the M8 series, newer than the M7, but those all seem to be water cooled. I’d also take the max pulse energy with a pinch of salt, as they don’t seem to be a consistent meaure. e.g. the 50W M8 shows a max pulse energy of 4, whereas the 200W models show 1.5 or 2 (or 200 in that one cloumn..)
I respectfully disagree; it’s a 1064nm MOPA laser, with pulse ranges from 6-500ns, repetition of 1-4000kHz. It’s very effective on metals! (also, I have the 20W version)
If you can provide the manuals, I can look at the differences. The YDFLP-E-300-M7-M-R’s peak power delivery was a bit disappointing, actually. I found the pulse energy chart of another one, the JPT M7 100W, and it has a peak of over 16KW at the start of the shorter Q-pulses. My 300W only goes to about 6.5KW.
The 60W goes even higher, 18KW.
The wattage is the max average energy it delivers. So yeah the 300W is a beast in theory, but engraving probably works on the peak power and these short power peaks are effectively cutting by explosion.
I saw some criticism of the E2, and it was worse than the E for peak power. We’d need to compare the pulse energy chart of a specific model to understand anything, though
It only had few feet of cable from the MOPA source to the galvo. But I took off the side and found she was hiding a secret
Yep, that’s about another 10 ft of fiber cable AND an equal distance of coiled slack in the copper galvo signal cable is also there.
