Thanks, Rob. Good morning, everyone. This morning, we reported first quarter 2023 revenue of $5.0 million, which compares to $4.2 million of revenue in Q1 2022. We placed 3 three Growth Direct Systems in the first quarter, compared to two in Q1 last year. Our Q1 2023 placements included one system that we previously forecasted in Q2, but we're able to pull into Q1. Product revenue, which is comprised of systems and consumables was $3.3 million in Q1, compared to $2.6 million in Q1 last year. The additional system placed in Q1 this year accounted for the majority of the year-over-year increase in product revenue. Consumables revenue grew 12%, compared to Q1 last year. Service revenue was $1.7 million in Q1 2023, compared to $1.6 million in Q1 last year. We completed the validation of two systems in the quarter, compared to nine in the prior year quarter. Validation revenue was lower in Q1 this year, primarily as a result of fewer system placements in 2022 versus 2021, which resulted in a lower volume of validation activity in the period. Also, as a reminder, several validations that we expected to complete in Q4 2021 were delayed into Q1 last year impacting the comparison. As of March 31, we had a total of 105 validated systems, which drove growth in service contract revenue of almost 50% in Q1 2023, more than offsetting the lower validation revenue in the quarter. First quarter recurring revenue increased 22% to $3.3 million, compared to $2.7 million in Q1 last year, driven by growth in both consumables and service contract revenue. Non-recurring revenue was $1.8 million in Q1, compared to $1.5 million in the prior year quarter. Turning to gross margins. Product margins were negative $1.7 million in Q1, compared to negative $1.8 million in the first quarter last year. The improvement was driven by continued progress on our manufacturing efficiency and product cost reduction initiatives and consumables. Despite the benefit of one incremental placement, system margins were lower in Q1 this year as they continue to be impacted by lower production volumes. Service margins were negative $0.1 million in Q1 2023, which was essentially flat, compared to Q1 last year. The benefit of higher service contract revenue and good service cost control were offset by lower validation revenue in Q1 this year. On a combined basis, our first quarter gross margin percentage was negative 36%, compared to negative 46% last year. The year-over-year improvement was largely a result of ongoing progress on our manufacturing efficiency and product cost reduction initiatives in both consumables and systems. We are also focused on increasing productivity and efficiency in our service business. We continue to expect these activities, as well as increasing volumes to lead us to positive gross margins in 2024. Moving down the P&L. Total operating expenses were $13.1 million in the first quarter, consisting of $3.5 million in sales and marketing, $3.2 million in R&D, and $6.5 million in G&A. Excluding $0.9 million in retention costs related to the restructuring plan we announced in August last year, the total OpEx was $12.2 million in Q1. This compares to total operating expenses of $13.1 million in the first quarter of 2022. Net loss was $13.9 million in Q1 2023. This compares to a net loss of $14.9 million in the first quarter last year. The year-over-year improvement was primarily due to higher interest income due to higher rates earned on our short and long-term investments. Net loss per share was $0.32 in Q1 2023, compared to net loss per share of $0.35 in the prior year quarter. With respect to non-cash expenses and capital expenditures, depreciation and amortization was $0.8 million. Stock compensation expense was $1.2 million and capital expenditures were $0.8 million in the first quarter of 2023. I'll now turn to our 2023 outlook for the full-year and the second quarter. We are reaffirming our previous full-year 2023 revenue guidance. We continue to expect revenue of at least $22 million, which assumes we will place at least 15 systems and represents growth of at least 30%. As Rob mentioned, we are still operating in a dynamic macroeconomic environment. We are seeing customer budgets receive increased scrutiny, which is affecting the timing and scale of some purchase decisions and could create revenue variability, especially in systems. Our guidance reflects some of this uncertainty, and we are continuously assessing the environment and monitoring customer interactions for changes in purchasing decisions. For the second quarter, we expect commercial revenue of at least $4 million, which assumes at least two system placements. From there, we expect to continue to build momentum as we move through the year with revenue and system placements accelerating as we move into the second half of 2023. We continue to expect to complete at least 14 validations in 2023 with at least two in the second quarter. With respect to validation revenue, we expect Q2 to be similar to Q1. We then expect validation revenue to increase in the second half compared to the first half, although there may be some quarter-to-quarter variability over the balance of the year, based on the timing of customer validation activities or previously placed systems, as well as the lag between system placements and related validation work for new system placements. Based on our revenue outlook, we expect our Q2 2023 gross margin to be lower than Q1 due to lower revenue and lower system production volumes. And then improve as the year progresses as our cost reduction and manufacturing efficiency initiatives generate additional benefits, especially in consumables and volume leverage increases. With respect to operating expenses, we continue to expect between 12.5 million and 13.5 million per quarter over the balance of 2023, with variability, mainly driven by non-recurring severance expenses that will impact Q2 and Q3 of this year, as well as the timing of certain new product development activities. Finally, we had approximately $122 million in cash, cash equivalents, and investments as of March 31. Our Q1 2023 cash burn included outflows related to the payment of several large 2022 expenses that we do not expect to recur over the balance of the year, including annual bonuses, and costs related to the strategic alternatives review we completed in Q4. We also expect to realize significant cash benefits from working capital management, particularly ongoing inventory reduction activities over the balance of the year. As a result, we continue to expect to end 2023 with cash and investments at or slightly below $100 million, which is consistent with the guidance we provided in March. We remain confident that this provides us with cash runway at least into 2026. That concludes my comments on our full-year and Q2 outlook. So, at this point, we'll open the call up for questions.
